This isn't like when a rising fighter in Jon Jones got to fight for the title 6 weeks after beating Bader. Weidman has no steam coming into this fight, and is highly inexperienced in the first place. He's big, got good grappling, mixes it up well. So what? If he'd beat Bisping or Vitor 6 weeks ago and was 100% healthy, on a high and diving right into this fight, the upset might be a tempting bet.
This is the wrong time for the boy to be fighting Anderson Silva.
