I don't see there being enough tournaments left for anyone to take PoY besides TJ. The only other person with multiple titles is Couch, and at this point, he'll have to work his way up through the WC quals to take the title. Not saying it can't be done, because it has, but I don't see it happening.
If anyone can win the next two majors, it's TJ. He's phenomenal on TV. I've only seen him bowl anything that can be called "bad" once. If Shafer had won today, Jackson Hewitt could go ahead and put up their checkbook.
