I completely disagree.
Carwin was booked to fight Brock originally because of the lack of real contenders in the heavyweight division. At the time he was coming off an impressive Gonzaga win and he had finished all of his fights in a couple of minutes. It sort of made sense to have Carwin as the next contender because Mir had just been whopped, Cain was too young, Big Nog and Couture were going against each other and JDS hadn't broken through like he has now.
But the illness that forced Brock to take time away from the cage was huge. Now all the other fighters in the division have moved a step up and Carwin has stayed in the same place, and that win against Gonzaga looks less credible with every month that passes. UFC 96 was a long, long time ago now.
It sucks for Carwin that he had his chance and now he has to win to get it again, but really, how many MMA fans would be happy to see Carwin getting a title shot from beating a gatekeeper nearly a year ago?
Going up against Frank Mir is a massive step up for him and personally I think he's going to lose.
How can you say that Carwin deserves a title shot right now over Cain or JDS?
Also, would you rather have this Carwin vs. Mir fight in the meantime or have Carwin shelved until at least May until Brock comes back? 14 months out of the game isn't good for a fighter with an 11-0 record who still needs to polish his game.
