I favor Spence to win, and hurt Mikey in the process, but personally I won't give him much credit. I base this all on size. When faced next to each other, the size disparity is blatantly obvious. I consider Mikey a superior technician and fighter overall, but Spence is a physical specimen in his prime. He's fresher, and huge for Mikey. I feel one punch from Spence can really affect Mikey bad. I don't think its a fair fight. Mikey is flabby at 140 already, and even at 135 he didn't look in prime physical form. With all that said, if Mikey figures Spence out and exposes his limitations, he can outbox him and get a huge upset. Spence is more flawed than Mikey, so you just never know. How much of a chance does Mikey have iyo?
