Over-rated - Here....HA, no really in a year where we've had four people get title shots coming off loses (Edgar, Tate, Sonnen, Diaz) this Weidman backlash is downright embarrassing. He's coming off a layoff...so's Anderson. He's not going to beat Silva oh he's not going to defeat the greatest of all time...clearly he's a bum. It's to soon, theirs like three LHW champions in the wings prepping for Anderson right now, and you have Vitor who's earned a rematch.
Now the second question, will he beat Anderson Silva....probably not, but he's got a better shot than the last guys that fought for the HW, LHW, and WW titles. The measure of a contender shouldn't be "can he beat Anderson Silva" because realistically who in that division can. The measure is he the best man for the job, he is the number one contender for the title.
