Nice read on how LSU gets to the 85 limit on scholarships and who's in/out for the 2012 season. http://www.tigerrag.com/?p=209802
Football attrition is kinda like eating out. You know weird things are going on in the back, we'd just rather not know.
The arbitrary 85 limit on scholarship players is mathematically stupid. Raise the limit to 100 and let every school have a hard limit of 25 new scholarship offers per year. The net result would be every school would be under 100 scholarship players as those that have true medical reason for not playing would not allow schools to "credit" those losses in order to sign more than 25 players in any year.
The smaller universities always fight for lower rosters because they can't make their programs pay for themselves. That's a major reason that the top half of Division I really should form their own division and play by big-boy rules.
Saban did the same thing here. Except he was trying to build the program up in the early 2000's, so he didn't cut too many guys. I don't think greyshirts were allowed then either.
LSU had TONS of talent on our roster before he even stepped on our campus. GDF, that's SEC math at it's finest there.
