No it's not.
There's looking bad, then there's looking like a complete and utter laughing stock and retiring in the post fight presser and admitting you shouldn't have come back
If you want to bet on him for fun because it's BJ and you're a fan, fine, but there's literally no reason to put a serious bet on him. He hasn't won a fight since 2010 and has took a beating that's sad to watch every time he's returned
I guess Yair could be wreckless and make a mistake on the ground early, but otherwise BJ is going to gas early like he always does and be a sitting duck. That's not enough for a serious bet.
If BJ comes out looking like a killer, I'll eat crow. But I won't regret not betting on him. There's literally no tape and no reason to believe he still has what it takes.
Also, he should be fighting a tune up like Siver or Miller. Not a legit prospect.
