This is a common misconception about the Belmont. Deep closers almost never win this race. It is usually won by a horse with tactical speed. I'm throwing out both deep closers for the win.
I handicapped the race and projected Sunriver to run a 104 beyer, Bluegrass Cat a 103, and Bob and John a 99, but there is no value there. I'm going with Oh So Awesome as a nice longshot. So far he hasn't shown the same ability as the rest, but his sire is a Breeders Cup classic winner, and I think he could surprise with some very vulnerable favorites.
