I am stoked about this!
I am surprised by the general consensus that Miller is mediocre. Sure, he might not be top 3 in the division, but he possesses some great skills (esp. in the jj dept).
I would love to see a TUF with Miller/Bisping or Miller/Sonnen. That would be great. He'd likely beat Bisping (IMO).
I think a good first fight would be Leben or Maia.
