Burns was 5'7 and defended the hw title at 168 pounds, a weight he easily could've made the mw limit if he'd drained a day ahead of time

What would happen in a mw fight with Hagler?

Hagler would stop him in about 4-6 rounds.

Nobody beats a prime Hagler. To determined, to well condoned,to much of everything. And yes i'm well aware of the P4P best Sugar Ray Robinson.
