Shaq cards have never been great cards in this game, in either season. He's a bad shooter, lacks offensive ability outside of dunking, and is most reliable on defense and rebounding.
The prototypical center for this game is KAT. An offensive, lanky, good rebounding, good shooting type.
Otherwise, going with a Shaq like center just means you're essentially relying on 4 players and not 5 to get you points.I only score with my PG, SG and SF. My PF's and Centers job is to get rebounds and put backs, we may have different play styles but ever since I moved away from scoring with those two guys I put up more points. If I'm in the paint with them I am looking for a dunk or layup, rebounds is 95% of what I want them for.
