He played like what, training camp, before going down with the injury?
Yeah, it takes time to recover, but if the Bears bring 2 more guards in as free agents, and then especially if they draft one, then someone is going to be the odd person out, and as of right now, that would be Carimi, as he was the worst of the linemen in question last year.
If they have confidence in him and that his problem was strictly the injury last year, they won't bring in 2+ extra guards, because he and Webb will make up the right side of that line next year.
