well I do like the way you think, the problem is lack of talent on this team. How long has Shanle been on this team now, and we never found someone better to replace him. How many # 1's we have on that side of the ball, and they sure as hell don't play like #1's. We have watched this team get beat under how many defensive coordinator's since SP time here? It's the players we have too slow, or just lack of talent all together.
The only ones I would keep as of right on on d Greer, and Lofton as a starter. Some others would keep for a back up.

But I will never throw in a towel on this team, I never have before and will not start now.

I still don't know why people continue to beat this dead horse. I don't think lack of talent is the issue here. Shanle has already been replaced in the starting lineup so that issue has already been addressed. He's best suited as a backup and that's exactly where he's at... finally.

Cam Jordan is having a well above average year. Jenkins has always has the talent to be one of the best starting FS's in the league. Roman Harper is a Pro Bowl SS... he's actually been average to solid this year in coverage. We have a good although struggling corner in Greer. Lofton is a solid MLB. Vilma looks pretty good on the outside as does a healthy Casillas. Bunkley was a #1 DT when we signed him from Denver. Patrick Robinson flashes brillance at times and looks like a deer in the headlights the other times... but talent is not the issues with him. Tez Wilson has flashed plenty of pass rushing potential and Galette is a solid backup. Will Smith is still average to solid.

Lack of talent is not the issue. Getting them to play at a consistent level is... and that's on both the coaches and the players.
