Offensive players scheduled to become unrestricted free agents for the Chargers include: WR Seyi Ajirotutu, WR Danario Alexander, RB Ronnie Brown, WR Lavelle Hawkins, OL Rich Ohrnberger and OL Chad Rinehart.

Beginning with the offensive linemen, Rinehart started 10 games at left guard and was part of an O-line that improved in 2013. Ohrnberger filled in at center when Nick Hardwick dealt with a concussion, and he performed well in a backup role. Depth on the offensive line was hard to come by last season, so do veterans like Rinehart and Ohrnberger immediately top the list of players to bring back?

Brown was also a key contributor in a reserve role. As the health of Ryan Mathews deteriorated down the stretch, Brown's workload increased toward the end of the regular season and into the postseason. With Mathews still prone to injury, is Brown a player you have to keep as an insurance policy?

We already discussed Alexander's situation earlier, but what about the rest of this group? Essentially, you have three big decisions to make in Rinehart, Ohrnberger and Brown. They are all veterans, and each of them is capable of fulfilling the same role given to them last season.

The one knock on Rinehart, however, is his injury-riddled past, which caught up with him again this year. Still, who's next in line should the Chargers decide to let him walk? Does the front office feel confident in drafting a player to come in and start right away? These are tough decisions that will need to be made.
