Your opponent is pretty well balanced across the board but his perimeter defense is a weakness.
What do you have by way of players with Jump Shot and Jump Range on your squad? If you've got some guards and a small forward with decent shooting range you could run a motion offense against him which would exploit his weakness.
Also, his inside scoring is slightly better than his outside scoring. If you play a 2/3 zone and make sure your forwards and centers have Inside Defense, you might be able to pull off an upset.
