Yes I think shotting (JS, JR and inside shot, and also some driving) is more important for PF and defending (inside D, rebounding and blocking) is more important for centers.
If it is clearly an issue of choosing 1 of the 2 for center he must choose wheter rebounding, or scoring will be most important for his center in this game. the game shape favours the first, but it's not to big deal since strong is already a high form to have.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
