To be fair, the UFC did what they always do - they hyped up Thales Leites as this big stud, huge prospect, 14-0 or 14-1 record at the time, etc. etc., taking on the champ. I remember this was one of the first AS fights I ever watched, and I was thinking as it unfolded, "This dude (Leites) sucks." Not impressed at all with Leites.
As far as Weidman goes, he has a decent shot IMO.
