Ah, that's a very tough one becuase your opponent changes his offensive tactic frequently.
Honestly, if i wasnt sure, i'd play man to man. Although your best players are centres so you could risk a 3-2 zone, and still hope for the rebounds (he played motion in last league match).
With regards to your offecne, your stregth is inside, so i would normally play look inside, however your opponent playes with a 2-3 zone, so it might be better to use a base offence.
I'm sorry it;s not too much help, but it's a tricky one. good luck.
