Usman is getting rematch immediately and deserves it. Even though he got knocked out with a kick overall he came out looking good in this.
Other than the first round when edwards took him down he had noting for Usman on the ground or standing up. Usman dominated, I don't think the the loss or edwards are in his head. If anything the pressure is on edwards because he did get dominated other than that kick and he was getting his ass whooped every round including the 5th with it was one minute left. he has to prove it was not a fluke.
Again the thing I HATE about the UFC is the ignorant fans want rock em, sock em robot style fighting. The fighters often times let the crowd dictate the fight, usman needs better head defense but other than that he should smother him, and fight his fight.
