It hasn't yet because this is the first year it's in place. 2, 3, 4 years down the road they will be hit very hard because they won't have depth and it will take them a while to re-stock to get to 85 players (with the 25/class max).
Currently, their lines are in trouble and if a few key players go down with injury they going to be in trouble. Yes this year they won't feel as much but if they go 9-3 next year, recruiting slips a little (not #1 anymore), then next year similar 9-3 or 8-4 record and they're not as elite any more.
