It depends are you going for offense or defense? If your going for defense I would trying for more speed down low, maybe even starting a solid SF at PF and a PF at C. If your going for offense I would not worry as much about the press and focus on your normal C/PF traits and just make sure you have a SF, SG, PG that are fast.
By the way Ath is not as important as Speed in press from what I have seen. This is at the D3 level though.
Oh and what I mean for the Off and Def is your team going to be a shutdown team or a light them up team?
