I don't think Stiverne was out of shape, he just has a soft body type and isn't use to having to throw so many punches. He went the full 12.

Bermane Stiverne's issue is his style is 100% counterpunching so if you dictate pace and distance he'll struggle. Ray Austin was outboxing him until he got caught. That said BWare IS a good heavyweight, he may not have fought a smart fight but he's a good fighter and I think he'd give troubles to a guy like Dereck Chisora, he'd be tough for Bryant Jennings, he'd be tough for Glazkov, he'd be tough for Andy Ruiz Jr.
