I see no reason whatsoever to rush him.
Transition him into bouts with better and better strikers. It's hard to get that experience in the gym.
He needs to learn to fight out of a few bad situations, dig deep and win, which I think he will do.
It's not good for anyone if they toss Bo in with a top 3 guy too soon and he gets taken out. Sure he will come back from a loss I am sure, but imagine the gate if a year or so from now he gets a title shot with a 15-0 resume and some big names on the most recent post of his hit list.
