Without those big physical guys, you also end up relying on the lower percentage three. In the end, both Collins and Carmody have centered their game on the three. Someone will say that's the "modern" game, and it should be when you have those guys. Most teams do not, especially when you're recruiting at the NU level.
Carmody was forever looking for his center who could open things up. Collins is forever looking for his 4 to do the same.
I hope someone looks toward West Layfayette where Painter obviously values size to keep some consistency. I've also read recently that Europe is starting to lean toward more traditional bigs.
