This may be the reason he is stocking up on guards.

His 2 bigs must be able to set picks to open up the 3 guards. Offensively, size/ height is not as much a concern. Defensively will be the problem in ACC play. Can we stop their bigs if they try to pound it inside?

But, the college game has changed so much that even teams with size allow their bigs to step out and shoot 3's. That's the chess match between coaches.
