Dick “Night Train” Lane. Antonio Gates. Over the years http://www.bearscheapstores.com/pat-o_donnell-jersey-cheap , there have been several undrafted free agents who have left indelible marks on the game of football. Despite not being seen as worthy enough of an NFL Draft selection, these players have overcome the odds and have gone on to become successful NFL players. Over the next few weeks, I’m going to take a look at of 10 of the undrafted free agents that the Chicago Bears signed this offseason to try and determine who stands the best chance of making it to the 53-man roster. In this article, we’ll take a look at the player who ranks fifth on the list: Maryland alumnus Cavon Walker.BackgroundWalker is coming off of a somewhat underwhelming senior season, as he totaled just 1.5 sacks and six tackles for a loss. He was able to hit a personal best 38 tackles, though, and had a career-high six tackles against Minnesota this season. Walker had 3.5 sacks, nine tackles for a loss and 31 tackles in 2016. He started his collegiate career as a linebacker at 229 pounds, but bulked up and moved to defensive line, where he played for his last three years at Maryland. Walker was a three-star recruit out of high school and was on the All-Met Second Team in his senior year at Friendship Collegiate Academy in Washington, D.C. The communications major was an honor roll student and has served as a volunteer at Positive Choices Football Camp in the Washington D.C. area.Skill setThere are no individual cut ups of Walker available online, but there are several highlight videos of his on YouTube, as well as full Maryland games.At six-foot-two and 284 pounds, Walker is slightly undersized for a 3-4 defensive end, which is where he fits in Chicago’s scheme. While he can’t change his height, gaining a little bit of weight could help his chances of carving out a long NFL career for himself. His smaller stature doesn’t affect his play, though, as Walker is a strong and tenacious player. He put up 31 reps on the bench press at his Pro Day, which would have tied him for the sixth-best total among defensive linemen at the 2018 NFL Combine. He does a good job of converting speed to power and has good drive in his lower body.While Walker’s production isn’t very good, his tape shows that he is a constant force in the backfield. He has good explosion off the ball for a player his size, and he can plug up holes against the run well. He’s good at reading option plays and does a great job of bringing ball carriers down in space. His motor also runs high on a consistent basis: he rarely takes a play off.One concern in Walker’s game is his inability to finish plays, especially on passing plays. He has the ability to shed blocks and to overwhelm offensive linemen with explosiveness, but he isn't very good at getting sacks. He doesn’t have fantastic speed in space and he can’t turn the corner very well, which limits his ability to get to the quarterback before he can get the pass off.Chances of making the 53-man rosterWalker faces pretty steep odds of making the 53-man roster. The defensive linemen on the final roster seem to be set in stone, so the former Terrapin likely won’t make the team this year. However, he has enough potential to make him a player worth keeping on the practice squad. If the Bears stick with that approach, then Walker could end up finding his way onto the active roster at some point during the regular season.Jacob Infante is a Chicago Bears writer at SB Nation’s Windy City Gridiron.

All of their backups - Blaine Gabbert, Drew Stanton and Matt Barkley - signed with different teams. Needless to say, Arizona was in need of a facelift at the most important position in football.To replenish their talent at the roster, the Cardinals dished out big bucks to sign both Sam Bradford and Mike Glennon in free agency, and they traded up five spots in the 2018 NFL Draft to select UCLA signal-caller Josh Rosen. An aggressive approach to ensure that they had found their franchise quarterback, Arizona has opted to give their rookie two players with starting experience to learn behind.While this strategy could very well benefit Rosen and, as a result, the Cardinals as a team in the future, it hasn’t proven to be fruitful in terms of current results.Through two weeks http://www.bearscheapstores.com/bryce-callahan-jersey-cheap , Arizona is 0-2 and has scored a combined six points in those contents. They have the fewest total offensive yards in the league by 96 yards, the fewest passing yards per game, the second-fewest rushing yards per game, and the fewest points per game by 8.5 points. Bradford has averaged four yards per passing attempt, which is also the lowest average in the league among starting quarterbacks.So, yeah. Things haven’t been ideal in the Copper State.The Cardinals have only allowed three sacks to start the year, but make no mistake about it: this is an offensive line that the Bears should run right through. Their starting offensive tackles are D.J. Humphries and Andre Smith, but Smith is out with an elbow injury. John Weltzel will be starting in his place at right tackle, projecting a major mismatch against Khalil Mack and a club-less Leonard Floyd. Without starting center A.Q. Shipley, Arizona boasts rookie Mason Cole in the lineup. While a solid athlete with potential, Cole lacks the functional strength to be able to contain Eddie Goldman on paper. Guards Mike Iupati and Justin Pugh have played at a high level in the past, and the former has proven to be a great run blocker in recent years. Pugh has had a rough start to the 2018 season, though, and Iupati hasn’t been stellar.Larry Fitzgerald, who has been playing at a high level since his rookie year in 2004, hasn’t shown any signs of slowing down with age. His impact, though, has been slightly downplayed to start the year with a lack of offensive talent around him. If rookie Christian Kirk is able to play after injuring his back in a car crash on Thursday, then Fitzgerald will have another solid weapon in the passing game around him. If not, though, then the Cardinals will have to rely on the likes of Chad Williams and J.J. Nelson - neither of whom having made a catch in the first two games of the year - to step up at wide receiver. Tight end Ricky Seals-Jones and running back Chase Edmonds have served as reliable weapons in the passing game, but neither has averaged greater than 5.1 yards per catch thus far.A major x-factor in Arizona’s offense is running back David Johnson. Despite being the bonafide top offensive player, Johnson has only 28 touches to start the year. His longest run to start the year is only 11 yards, and he has averaged 3.9 yards per carry. Although his performance in 2018 hasn’t been up to par with what many have expected of him, he is still a proven, Pro Bowl-caliber talent. Even though the Cardinals haven’t used him very well, he is still a threat to break out and have a big game.Luckily for the Bears, they have more than enough pieces to contain Johnson. Roquan Smith displayed incredible direction-changing abilities in coverage against the Seattle Seahawks, and Danny Trevathan has gotten off to a hot start to the season thus far. Though neither Adrian Amos nor Eddie Jackson have been fantastic to start the year, neither has been necessarily bad, either.All in all, though, the Cardinals won’t be able to consistently move the ball down the field if Bradford and the offensive line don’t show up. So far this year, they haven’t been able to do so. Their performances directly affect how the likes of Johnson and Fitzgerald do. Given their recent inefficiencies, the Bears could be in for their best defensive performance yet.
