Mike McCoy a day after the team was blown out at home by the Denver Broncos on national television.First-year head coach Steve Wilks said Friday that quarterbacks coach Byron Leftwich will take over the job for a club that is 1-6 Los Angeles Chargers Hoodie , the worst record in the league."Seven weeks into the season, based off where we were from the standpoint of production on the offensive side of the ball, I felt the need to make a change, and that's what I did," Wilks said at a news conference.McCoy, former head coach of the San Diego Chargers, was fired for the second time in as many seasons. He was let go after 10 games as Broncos coordinator last year.The Cardinals lost 45-10 on Thursday night, trailing 21-3 after one quarter and 35-3 at the half. Wilks called the effort "embarrassing."But he said his decision to replace McCoy was not based on that one game alone."We weren't productive enough," Wilks said. "Let's just say that, and that may be an understatement."The Cardinals have lost their first four home games for the first time since 1979, nearly a decade before the franchise moved from St. Louis to the desert.Arizona entered Thursday night's game ranked last in the NFL in offense and rushing offense and next-to-last in passing offense. The Cardinals have just 10 offensive touchdowns in seven games.Asked if Leftwich should be considered an "interim" coordinator, Wilks said, "Right now, it's hard to say anybody is going to be permanent."Leftwich is a holdover from the staff of coach Bruce Arians, who retired after last season and was known for his dynamic offense."You definitely want to be able to try to get David Johnson going in the run game as well as the pass game," Wilks said. "With Byron being here before and being part of that and understanding some of the success he's had in the past, hopefully we can tap back into some of the things David was doing in the past."Leftwich was a coaching intern when Johnson led the league in yards from scrimmage and touchdowns two years ago. He was promoted to quarterbacks coach last year and called plays in the preseason this year.Wilks has a coaching background entirely on defense. He was defensive coordinator of the Carolina Panthers last year. He entrusted the offense to McCoy, figuring the experience at head coach would help.But the offense sputtered from the beginning, especially in attempts to get the ground game moving.The Cardinals switched from Sam Bradford to rookie Josh Rosen at quarterback three games into the season and Rosen had a rough night against Denver, throwing three interceptions — two returned for touchdowns — and fumbling the ball away twice.Rosen was injured on his final play and was in a walking boot with a sprained toe on his left foot."He should be fine and ready to go next week," Wilks said. "We have 10 days and based off what the trainers are saying there shouldn't be any setbacks."The Cardinals don't play again until Oct. 28 Customized Los Angeles Chargers Jerseys , when they host San Francisco.The 38-year-old Leftwich, a first-round draft pick out of Marshall, played quarterback in the NFL for 10 seasons with four teams — Jacksonville, Atlanta, Tampa Bay and Pittsburgh.Rosen has been Leftwich's primary project and the two already have a close relationship. Wilks talked about the need to streamline the offense."I think what Byron is going to do, from what he and I have talked about, is really trying to figure out what Josh does well," Wilks said. "That's the key thing. When you have a young quarterback, we want to make sure that we're putting him in a position to where he can go out there and not have to think so much. Those are the things that we've talked about."Wilks said Rosen is very intelligent, that's not the problem."I think it's clarity," Wilks said. "That's what we need, and we didn't have that. We've got to have clarity in exactly what we're doing in certain situations."McCoy, who has worked in the NFL since 2000, was a highly successful offensive coordinator in a first stint with Denver, leading to him being hired as head coach by the Chargers in 2013. He was fired after four seasons with the Chargers.Please don’t let the name ‘Jack Boys’ stick There are a few nicknames and monikers that become so ingrained into the sport of football that they becomeinseparable from the game itself. The most famous is probably the concept of a “hail Mary” pass, which is now more often thought of and referred to as a football concept than the pious act itself. This relational transformation is known as ubiquity, and boy do sports love their ubiquity!The concept of tying a memorable phrase to a sports figure or action is not new. Gladiators, including the famous animal fighter Carpophorus, were given nicknames that were meant to be both memorable and descriptive. “The King of the Beasts” was his title, and he triumphed in one match that pitted him against a bear, a lion and a leopard www.authenticlosangeleschargers.com , all of which were released to attack him at once. Another time, he killed 20 separate animals in one battle, using only his bare hands as weapons. In the modern tongue, this dude was ‘legit.’Carpophorus (Karpophoros, Carpoforus, Carpoforo) is a name of Greek origin that means “fruit-bearer.”It seems that bear was more apt than fruit.RomeNicknames can also cover multitudes of athletes. Fast-forward to more modern day examples and you have the Steelers’ Steel Curtain of the 1970s. This title is one that stuck because it does the perfect job of balancing known phraseology with descriptions of the force’s qualities. The nickname “Steel Curtain,” a play on the phrase “Iron Curtain” popularized by former British Prime Minister Winston Churchill, originated in a 1971 contest sponsored by Pittsburgh radio station WTAE to name the defense. It works so well because it blends the team’s character (steel, quite obviously, and being a tremendous, fearsome force like the Iron Curtain) with a memorable moniker. When a nickname works on this many levels, it sticks around. There’s the Monsters of the Midway, the Big Blue Wrecking Crew, and many others that stick because of that balance of name and on-field work.The Seattle Seahawks’ incredible defense in 2011+ earned it the nickname ‘The Legion of Boom.’Although specifically referring to the original group consisting of the main starters in the Seahawks secondary: Richard Sherman, Earl Thomas, Kam Chancellor, Brandon Browner and Byron Maxwell, both the team and its fans are trying to keep the name around even after the stars departed. The name itself was coined in 2012 from a twitter contest suggested by radio personalities. The connection to the original Legion of Boom was pretty weak in 2017, but they found something marketable, and I can’t blame them for wanting to keep it going. Here in 2018, they are now firmly trying to convince us that the Legion of Boom was not a set of people Los Angeles Chargers T-Shirt , but rather whoever makes up the secondary in a given year. I wish their marketing staff luck in that endeavor, because only continued dominance will make that at all possible. Even the Steel Curtain got trimmed before long.And now we find that the LA Chargers have their own nickname:The Jack Boys. This stems from their use of defensive coordinator Gus Bradley, who oversaw the reign of the Legion of Boom in Seattle. The Chargers certainly do have some incredible power and potential in their defensive ranks, including Casey Hayward, Jahleel Addae, and soon to be introducing Derwin James. This defense has power, it has hunger, and it has an identity- but where did Jack Boys come from?According to ESPN,The name was first brought up during a team meeting back in San Diego, and coined by teammate Adrian McDonald. It refers to the term Jack Boy, which Urban Dictionary defines as: It is also the name of a gang that was known for their car jacking, though some reports indicated that they only started their escapades in a Robin Hood-esque spree aimed at robbing drug dealers. Either way, they soon devolved into the same things they were theoretically rallying against. The leader received a grand prize of 15 life sentences, plus 290 years on top of that. With good behavior, he should be able to cut that in half.In summary, the Chargers have all of the potential pieces in place to have a generational defensive force. The current name for this force is, apparently, the Jack Boys. Photo by Tom Pennington/Getty ImagesWithout delving into the reasons for why this name could be confusing and is not, necessarily, the kind of title that invokes fear in an opponent, the big name defenses of the past have seen the most success by trusting their fans to come up with appropriate names. This defense seems to pride themselves on their ability to intercept footballs Los Angeles Chargers Hats , which is a great thematic starting ground. We’ve got shadowy figures of all kinds to word play with, and we’ve got the full force of the internet to try and find a catchier name before the Jack Boys tries to catch on in anything but a sarcastic way.So, let’s see what we have as far as things to pair with. We have references to electricity and charging, sure. We have Hollywood, movies, and the ocean. Okay, that’s material, too. There’s California, the West Coast, traffic, and that’s pretty much LA in a nutshell. What we need is some sort of... grand theft motto. Citizen Pain, Disarmageddon, Band of Smothers, no, now we’re too far into Hollywoodland. Maybe the lightning motif?Lightning and Plunder?Hmm. Okay, I’ll be honest, I checked out once I hit Inglorious Grafters. I need help— what names do YOU have?-Jason “Puns of steel” Michaels
