Speed no, can he make up the difference through length and distance to neutralize Vitor's speed? Most likely. We compliment JBJ on his athletic and genetic blessings, but one thing he rarely gets credit on is his footwork which is top notch.
This will be a closer and more dangerous fight for JBJ, Vitor's can knock anyone out and unlike Hendo, has the speed, technique and offensive tools to do so. He is also one of the best finishers in the game, if he hurts you once you might never recover.
I still have JBJ as the favorite, but I wouldn't sleep on Vitor.
