Well first of all you just gave him some valuable information by posting your enthusiam on here, but it doesn't look like he is very active, he never changes his tactics.
That being said, you have two things going for you. 1. The game is a home game for you so you have home court advantage. 2. He has played inside box and run and gun every single game this season. Another thing I saw is that he has played the same effort level as his opponent every game this season. This means he either has extremely high enthusiasm or it is at a 5. My guess is he has played normal every game, so his enthusiasm is probably at 5.
So I think you should be able to TIE and beat him if you choose the correct tactics. Since he always plays Run and Gun, I would play 3-2 on defense. He always plays inside box so I would play something outside, like motion or run and gun on offense.
Looking at your roster compared to his, you seem to match up pretty well against him at every position, and your SG is better than his. The only way he could beat you is by Crunch Timing you or if his enthusiasm is much higher than yours, which it probably isn't.
Hope this helps, Good Luck!
