Option 2.

Since I just went from Chicago to Winnipeg, I am going to choose to sabotage the Chicago Syndicate. I would do this by getting a calling service on all of my friends on the team, to ring their phones over and over again all night before the game. Since I have most of their addresses and phone numbers, this would be really easy to do. I am just that devious that I would not get caught, because who would suspect their dear old friend Mat. Along with that, I would get food delivered to the addresses of all the players the night before, but spike it with things they are not allowed to eat. So they would be sleep deprived, belly full of bad food right before they have to play a big game. Since I also grew up in the Chicago rink, I would visit the place the night before, for old times sake, and unscrew all the benches on the home side, so it slides off right as they all go to sit down.
