This is a key point. PG & C are still highly position based roles while the 2,3, & 4 are more interchangeable. Also,
remember BYU was #296 in luck factor last year on kenpom.com. Had they had average luck, they would have logged two more wins.
Assuming average luck.
Players jelling is one thing, BYU is better shape that way than most teams.
Massive new coaching staff with roles that take time to define, worry me a little.
But in the absence of injuries to Keba, Fouss, Hall, or Demin, you are right to point out that PG and Center are very much stronger.
