Well before Matt wants to fight Alves lets see if Alves can even make weight for his fight with GSP. He has missed weight almost as much as Gina has and has gotten caught using diuretics to make weight. He also came in 4 pounds over for the Hughes fight and said it was because he couldn't train for the weight cut because of a injury

. But yet he showed no signs of any injury in the fight at all. The only person that showed an injury was Matt and his knee. You could tell it was bothering him a lot and affect him heavily in the fight. This also helped Alves in the fight because he wasn't affected by the weight cut that it does to other fighters.
Matt was a dominant champ for a long time and I would never count the guy out of a rematch. The only person at WW I don't think Matt has much of a chance beating is GSP. This is due to the fact GSP's wrestling is just on another level than anyone in the UFC.
Love or hate the guy he was one of the greatest fighters ever at WW and I feel still has some fights left in him. Unlike Ken, Frank, Wandy, and Chuck who show major signs that its time to hang it up.
