Possibly the most anticipated comeback in the last couple of years was Vitor "The Phenom" Belfort.  I, for one, was definitely excited having followed his career ever since the TKO win over Tank Abbott.  When I heard he was returning, I told all of my buddies who also follow the MMA world to get ready.  I don't think anyone was let down by his dominating performance over Rich Franklin.  And it appeared to me that the UFC Middleweight division was about to get a lot more exciting.  I quickly predicted a Belfort vs. Silva match and wasn't let down by Dana White.  But then the worst happened.  Vitor pulled up injured again.  So back to the drawing board for Dana White.  Who could possibly step in?  Chael Sonnen?  Ok, not a bad choice, so of course he gets injured.  Now it falls to Damien Maia.  Did anybody really think he was ready for The Spider?  Now, it's back on Sonnen, and while I expect it to be a much more exciting fight, I seriously doubt we see a new champion.  So the question is:  Can Vitor return from another injury?  Can he fight Anderson right away without a warm up fight?  Could he beat Anderson even if he had remained healthy?  My heart tells me to say yes for all three questions, but my brain has some serious reservations.  Without a doubt, Vitor is the closes thing the UFC has to a real competitor for Anderson Silva right now.  But is he enough?  Thoughts?
