A combination of things. DLH was **** at the weight, he was overtrained to make it, focused too much on getting down in weight too early. Dont forget Roach had trained DLH as well, he wouldnt have taken the fight if he didnt think Pac had a really good chance to beat him at 147, he knew a lot more about Pac's chances than the general public.
How dare that former 96 pound flyweight cherrypick these future Hall Of Famers like that! Pac, you are a cherry picker!
