I agree, and out of the USA team members Bergman has probably historically been the most immune to pressure and least likely to lose confidence. Yes, including over Shane, who is fabulous when he is ahead or thinks he has the best of it, but who is often not real mentally strong when he is behind or thinks he has the worst of it (and no doubt Shane thinks he has the worst of it playing Filler right now even though he would likely never admit to it). But I could see Skyler or SVB being the best pick depending on how they perform tomorrow and their confidence levels.
Like sjm said, Johan probably wouldn't ever put anybody but Shane in as captain's pick for the tie breaker match, but I think he should give it some very serious consideration depending on how Shane plays and his confidence level tomorrow (and Johan has been known to do unpopular things and stick to his guns and not cave to public pressure in the past). Of course I am also one of the people that feel Shane should have been left completely off the team at least one of the years in the past, and there was a real strong argument to be made for doing that, but Johan obviously never did. For better or worse Shane will almost surely end up being captain's pick if needed.
