Exactly my approach to this match up. Can't see no advantage for Browne bar he being taller, but since Nelson dismantled taller guys while having breakfast, back to zero advantage.
Guess he skipped breakfast against Werdum/Rothwell/Dos Santos. Really as every Roy Nelson fight comes down to is can Roy one-punch Browne and is Browne susceptible to the one-punch. I don't think so, I bet on Browne.
