In addition to free-agent addition Kevin Burnett, the team has three players who started at least seven games last season -- Stephen Cooper (12), Tim Dobbins (eight) and Matt Wilhelm (seven) -- and special-teams stalwart Brandon Siler.
But even with the top-five locked in place, there may be room for one more. The Chargers carried six inside linebackers for a stretch last season, when Anthony Waters and Derek Smith were also on the roster.
LB Jasper Brinkley
Brinkley (6-foot-2, 252 pounds) went to the Combine looking to show scouts he is fully recovered from a season-ending knee injury he suffered in 2007. He did exactly that, running a respectable 4.72 in the 40-yard dash.
His other numbers were even better, as he proved to have impressive strength (26 bench-press reps) and a long wingspan (33 inches).
Also while in Indianapolis, Brinkley sat down with SDBoltReport.com correspondent Erin Murphy for a quick five-question interview.
Erin Murphy: How's this whole process been going for you?
Jasper Brinkley: It's a different process, but for the most part it's pretty exciting.
EM: What do you hope to show all the scouts in attendance?
JB: I hope to show all the teams that I'm 100 percent recovered from the injury that I had in 2007. I want to get the confidence back in the scouts.
EM: What will you bring to the team that drafts you?
JB: Leadership. I'm a great character guy and somebody you can build a team around.
EM: If you weren't playing professional football, what would you do for a career?
JB: I want to be coaching on the high school level. My high school coach, Luther Welsh, was very inspirational. He was hard-nosed and always told us you have to go out there and establish yourself as an aggressive player.
EM: Have you gotten to talk to the Chargers this week?
JB: Yes, I think I have, informally.
