Sonnen named Aspinall's main problem

Chael Sonnen, former UFC fighter and current commentator and analyst, called out the main problem with the promotion's interim heavyweight champion Tom Aspinall.

"I don't think you realize it, but his quick wins are useless - there's nothing good about them. It looks good, and it sounds good, but it's not good! When you find yourself in a fight that's tougher than you're used to, it's going to be a problem. This is the reason Ronda Rousey lost to Holly Holm. Not because she missed a leg kick to the head, but because the six other girls before her together lasted less than Holly. It's a problem for everyone, and there's nothing you can do about it."
