Penn is listed at 5'9" and Page is listed at 5'10", both are probably slightly smaller. Obviously Page can play at a d-1 level but he is a small guy which has to have some negative impact on defense and rebounding. Add to that playing a 4 guard lineup and Marshall only being 6'6" and I don't see how that team wins when they are not hitting 3s at a very high percentage. Compare that to OU that will like start one guy at 5'11" (TMG), WW at 6'4", Crocker at 6'6", Gallon at 6'9" and Allen at 6'11". (Plus OU could put move WW to point and put Willis, Pledger or Davis on the floor who are all substantially taller than Page and Penn).
I don't see how Page or Penn can stop Warren, Pledger, or Willis. All three can shoot over the smaller defender. This is especially true if you give them a little room because you have to respect their ability to drive..
There will be d-II and juco teams with bigger lineups than OSU. I realize the guys playing at OSU are better players but I have to think the lack of size is going to cost them some games ultimately prevent them from being a serious contender.
