Before the Spence fight I'd actually favored Mikey slightly or a 50-50, he is a very good counter-puncher and he can really crack at 135. I could definitely see him catching Loma coming in. With that said I'm not sure I'd pick him now, he'd probably struggle to make weight, he was never a top shape athelte to begin with but it would be even worse if he'd have to cut back to 135.
Mikey should have stayed at 135/140 and take the big money fight with Loma instead the big money fight with Spence, he'd be better off.
Now he's about to stay at 147 where he almost got shut out by Spence even though he could still make 140. I think he's only in it for the money unfortunately. No other reason why a top boxer would stay in a division where it was proven painfully obviously that he's not the best.
