Scott Mruczkowski (6-foot-5, 320 pounds) is a versatile, intelligent lineman. He has started just two games in his four-year career, both at left guard, but he has the ability to back up every position except left tackle.
Mruczkowski plays with power, leverage and grit. He has limited foot speed and poor lateral quickness -- he allowed 1.5 sacks in his lone start last season -- but he makes up for those deficiencies with technique and want-to.
With Jeremy Newberry and Cory Withrow no longer on the roster, Mruczkowski will likely be the backup center this season. Mruczkowski played center during his college days at Bowling Green, and although he has yet to start at the hub position in the NFL, he still receives regular snaps there in practice.
"He's great at center because of his leadership abilities and his long-snapping skills," said Gregg Brandon, Mruczkowski's head coach at Bowling Green.
OL Tyronne Green
Green (6-foot-2, 308 pounds) is one of the few players who can match Mruczkowski's versatility. He arrived at Auburn as a defensive tackle before moving to the offensive line, where he played both guard and center.
Green was energized when the Chargers called his name with the No. 133 overall pick in this year's draft. He believes he is a great fit in San Diego's offense and is excited to be reunited with former college teammate Marcus McNeill.
There's only one hiccup with the union between the Chargers and Green. A.J. Smith stated after the draft that Green was picked as a center, but Green believes he should be lining up at guard -- at least for now.
"[Guard is] really where I've been playing the last few years and it's what I know for sure," he said. "[The Chargers are] very active at guard, just combo blocking with the centers and pulling out. This offense has a lot of pull plays here and there, so I think the guard role is best, at least right now."
Green added that he is willing to play wherever the coaching staff wants him. His first priority is to learn the playbook and adjust to the speed of the NFL. After that, he believes he can be a versatile swingman in the mold of Mruczkowski.
"I believe I can play a pretty similar role because I'm an athletic guy," Green said.
The Chargers will likely be forced to choose between Mruczkowski and Green when it comes time to set the active list on game days. The team only keeps eight offensive linemen active; that leaves room for the five starters, L.J. Shelton, the loser of the Kynan Forney-Louis Vasquez battle, and either Mruczkowski or Green.
Mruczkowski, who signed a three-year contract extension last offseason, has the early advantage; it would come as no surprise if his strong play forces Green to spend his rookie season on the inactive list. However, the rookie from Auburn is too talented to hold down for long. Green will have a chance to carve out a role sooner than later, especially if the offensive line doesn't improve by leaps and bounds from last season.
