It's the opposite. Wins over Boone, Dawson, Cloud, Bellew, Fonfara x2, Bika, Williams Jr. and a draw w Jack and valiant loss to Gvoz as a fossil isn't bad at all. Most write him off. He could've gotten more done though.
You could say the exact same thing for Bob Foster (Tiger at 175 and pushing 40 years old wasn't great).
I’d just about favour Stevenson being the bigger guy. However if this turns out to be a firefight I would never write Nigel Benn off in those circumstances. It’s conceivable that Stevenson could be taken out.
