Mike did great plays twice. The one with the paddle was fantastic, since no one wanted to pick 1 knowing that they had no chance of winning any money if they did since he said he's picking it. And then with the last game, if he hadn't offered to split the briefcase, they could have forsaken the boost, and agreed to split the money each round and block his medal, picking everything but the 0, splitting the money between themselves and ensuring no medals would be gained, at least until the last round of it. That would give them the maximum amount and also prevented Mike from getting any more medals. All together, wholesome ending, good strategy :)
