Yep. The "4" in Beilein's offense isn't going to be handling the ball on the PnR; his role will either be finish at the rim or hit the shot on the pop. Or to be a floor spacer and hit shots when the ball is swung around the perimeter.
The bigger issue for that position is finding someone who can compete on the glass and defend B1G caliber power forwards. In this system, those are more important skills for the position than a "4" who can break guys down off the dribble, IMO.
In a Steve Fisher offense, for example, it was more important to have a Chris Weber or Mo Taylor or Robert Traylor who could take opposing bigs off the dribble. Different fits for different systems.
