This is even more simple when fighters who are drained fight at lower weights they can get hurt or dropped. See Oscar De La Hoya for example. Loma got dropped by a guy who's not know for his power yet you claim that he doesn't have chin issues a clear agenda if I ever saw one.
Just because you have your blinkers on and cant see the vulnerability crawford showed there, and what danger it may be in fighting bigger and better men. theres no agenda here, i actually rate crawford highly, i just say it how it is. also a tighter defence is better than having a iron jaw, vasyl lomanchko has both, but most importantly he has a tight defence, crawford is a top boxer that has shown a leaky defence, it wont wash at 147lbs.
