He did not take any drugs which would enhance his fighting skills/abilities or training regiments, its just him being punished for being found out. This changes nothing in his fighting ability, though. Which is why its going to be an easy win.
I see no reason to punish him for his drug habit other than deceiving his fans who bet money on him to be physically and mentally healthy in his fights. His habit might get him in prison or he might have a heart attack. I guess this makes us feel a bit uneasy to bet on him.
A drug test is part of any sports regulation so David being caught positive deserved punishment. And who knows, his family or any member of his family is also part of the syndicate. Do you remember when his older brother Jose another big potential in boxing was shot and hit in the leg? That injury affected Jose's footwork and was stopped by Crawford.
Anyways, I also think David will be like a bull in the ring, too strong and too heavy-handed against Caleb. Caleb needs to hit David with a damaging shot to get his respect, otherwise, David will just continue to become aggressive and might even open himself to lure Caleb's defense. I see a David stoppage in the 2nd half of the fight but I am hoping for the underdog Caleb to pull an upset.
David Benavidez getting his punishment in the past was already enough for him because every move has always a consequence entailed, but speculating or accusing that maybe one or two of his family are also using it? That's quite a bit too much mate, and if ever you are right, we don't have any right to prosecute them because that's their personal life.
I bet you wouldn't want the same thing too and hear that somebody is accusing you or a member of your family, right? So, let's just focus on the topic and let their personal lives out of this.
