DLH to his credit has fought the best and yep lost a few along the way. Tito and the second Mosley fight he was hard done by. The only one he missed along the way was probably Tszyu. Nobody can knock his record and who he has fought. Win, lose or draw against PBF his legacy in the sport is assured.
I can't see the point in him continuing if he beats PBF unless he gets Winky at 154 and i don't think that is likely.
