This is a trick question. Not which is the best (that'd almost HAVE to be Michigan State), but which group of freshmen will have the best overall COLLEGIATE careers?
Cook - likely to go early after year 2 or 3
Bridges - likely gone this year
Nebrasketball (here if only because they could all stay and could all develop really well... but probably won't)
Certainly, I hope Iowa does, and if Cook stays for 3 years (let alone 4), they'll have a VERY good chance at being the best. Maryland looks pretty dangerous, too, and not a likely group to go pro early right now. Penn State is sneaky promising, but I think they'll go pro early. Michigan State, obviously, is loaded, but there's no way Bridges stays past this year.
