1st thing that I have to tell you: don't compare teams, compare stats which you see at the end of a game...So, if he always plays inside, you have to put 2-3, no question about this. But, take in count his guards and their higher shot %...but if he plays inside, this is not a big problem
Offensive tactic is also not a problem ,if he plays 3-2 defense. So, hope he won't change tactics on your match ;)
