I think it is a mix of what they're paying Brock compared to other fighters, plus Brock has said in interviews he's asked them to pair him up against the best right away.
I don't think it's a problem for Brock though. I mean if he loses to Couture, well he lost to Randy Couture
, something even the top guys have done in the last few years. I don't think it'll make Brock look too bad to lose to Couture in his 3rd UFC fight.
What I will bitch about is the fact that this for for the heavyweight title. Kimbo I don't think is ready for main events yet, and I feel the same about Brock. Even worse in Brock's case because I don't see what he has done in order to earn a title shot against Couture, especially when there's already an automatic #1 contender in Nogueira, plus I'd think Mir ranks over Brock easily. This just throws how they determine #1 contenders right out the window, which is just stupid. Brock's last win wasn't impressive enough for even a fight to become #1 contender.
