Bomac is P4P one of the dumbest people in the sport, all you have to do is listen to his undercard ESPN+ commentary, and that becomes stunningly clear within seconds. I'll let you in on a little something, the secret to Crawford's success.... is Crawford.
I remember watching a Crawford interview, probably about 4 or 5 years ago IIRC, where the interviewer asked Crawford about his promotional stablemate Loma who was due to fight that week or not long after and Big Mac interjected saying that he didn't care if Loma lost the fight (he clearly meant he hoped he would lose). Loma had only had a couple of fights back (anything from 1-4 fights IIRC) then and there was absolutely no reason for him to say that. I've disliked Big Mac ever since then.
Re. Manny vs Crawford. Big Mac is right about 'timing' being key because a prime Manny would've beat the soul out of his boy.
He's old already. Being old doesn't seem to be an issue for Manny. Bomac picked the wrong boxing cliche.... lol
