There will be at most two previous medalists: Woods, and Bassett if he wins the spot and a medal. It may be deep for a post-NCAA bracket, but far from the deepest bracket ever.
Going back just two years ago, 86 featured world champ and previous p4p Taylor, world champ Zahid, world champ Hidlay, olympic medalist and hot pisser Brooks, world team members Marstellar and Downey, 2x (3x??) world team alternate Dieringer, and 5x champ Starocci. And that is just off the top of my head, I'm sure that there have been tougher OTT brackets.
