If you watched the game, every post pass draws a double team from the weakside....you simply cannot get the ball inside unless the player has a size advantage or an ability to face the defender and make a pass. You cannot post up in college basketball unless the bigs have mobility to get around their defenders quickly.
The game requires a skill set in the low post. And if you guard the post like RU does, without double teams, you have to have quickness to close out on shooters, if the big can make a pass play from the post.
These are not coaching related items, it comes down to playmaking, experience and talent from the bigs or whomever is posting up. The reason why there were so many positive things about Myles Johnson was his passing ability. But Myles fouls a lot and wasn't able to keep up with Pardon, so he couldn't play as much.
On the surface, a lot of the freshman have performed to the levels many expected. I think in some cases, players like Mathis have elevated from 6th or 7th man in the rotation to bonafide contributor.
