#5 Tyron Woodley
Tyron Woodley is one of the baddest men on the planet, and he is rightly the Welterweight Champion of the world. However, he also has a tendency to complain about quite a lot of issues which is why we believe he'd be a great whiny manager in the WWE one day. You could turn him into an Abraham Washington character of sorts, constantly lauding over his own greatness until one or two things don't go his way.
Woodley could work well with a tag team, yelling instructions from ringside as if he was more of a motivational coach than a manager. Obviously, he's probably more than capable of stepping into the ring himself, but to start off with, we'd rather see what Woodley can do on the microphone because his UFC tenure suggests that there's a lot of potential there.
