Stuve aint bad. He is still young also. He has stated that he wants to bulk over then ext couple of years so I would expect him to be a little bigger than his last fight. He is 6'11'' as it is.
I don't know anything about Brownes BJJ/wrestling. Do you know anything?
He is big so I assume he won't be easy for Struve to take down if he wants to go that route. Struve is pretty good off his back though, if browne takes him down. I could see Browne outstriking him or muscling him against the cage. I think the latter would be effective. He did well against Kongo but he was just kinda winging crazy punches. That is sort of dangerous IMO. Struve has ko power.
