I don't know about all of Sheed's trashtalking, but with the exception of his last guarantee, haven't the Pistons won every other game he guaranteed in the past? If I'm right in my memory, it seems to be a good way to fire up the rest of the Pistons (again, with the exception of game 4). In any case, I'm pretty sure I'd hate Sheed's guts if he were on any other team

.
As for the Pistons in game 6, I have a feeling they are going to have a tough time winning, but if they do, I think they'll take game 7, too.
