I don't think Vitor needs to even catch Rockhold. Vitor is the better striker. He can win without getting a stoppage.
I call BS on that. 9 of Belfort's fights have gone the distance and he's only won 4 times. The 4 guys he beat have even worse decision records than he does. He's never even been in a 5 round fight, while Rockhold has been in 2 and looked fantastic throughout.
Belfort needs the finish, no two ways about it.
