Redhsirting still seems mostly appropriate for bigs who need the time for proper physical development to play in leagues with bulked up upperclassmen. If your recruiting is good, you shouldn't need to redshirt anyone else, and the depth you recruit to fill out your bench is unlikely to develop into star material with an extra year anyway, so their gain is marginal. I think players now have a much better idea of where they fit in the sporting universe, and with the dramatic expansion of professional playing options, they know if they have any kind of game in D1 ball, they'll land a job somewhere. If there's a diamond in the rough, it'll come out during the course of a season, at least in practice. When guys are still benchwarmers at the end of a freshmen season, that's pretty much all they were ever going to be. They're depth or practice talent. Nothing more.
