Why should he CT?
He's already in 1st and is playing the 2nd place team.
If he loses this game, he will still be tied. Ties are broken first by PD, and his PD is more than a 100 points higher than the 2nd place team, so isnt he guaranteed the 1st seed either way?
Plus he has been TIEing and has a high enthusiasm that would be cut in half if he CT.
