It makes sense to me that Nebraska could have a good amount of transition.
If the regimen for a football player here is: To bed early, early to rise because Duval says its part of the program, and the practices are early so you better....and its a fast paced practice, you've got little time to screw around with politicking with the coaches or late at night playing Madden screwing around. You are either moving up or just getting gassed each day I assume, with a "faster" paced practice at Nebraska...from what I gathered at the hiring of the staff..
Sounds like its a real grind during the week and if Frost can pull in #15 classes and possibly higher each year, I can't see a bunch of players that are decent to highly recruited, wanting to bust their butt and not move up into the 2 deep...let alone the eventual ones who think they're better and transfer because they don't grade as good going up against college competition in practice.
