For Bradley, his options are somewhat limited. I don't know his contract situation, but with Top Rank it is highly improbable that he gets a fight with Mayweather. That's unfortunate, since he would likely give Mayweather a very tough contest.
It looks like Amir Khan is off the Dec. 7 date at Barclays, instead focusing on a May date with Floyd. Looks like Devon Alexander will instead take on Shawn Porter.
Marquez clearly lost this fight. Watching it live, I scored it 8-4 for Bradley but expected widely divergent scorecards. I thought the fight might have gone either way, but the consensus seems to be that Bradley was a very deserving victor in this fight.
I would not be surprised if Marquez does retire. He only fought once this year, and seems only interested in big money PPV events at this point. Besides a 5th fight with Pacquiao, there just aren't many fights to be made that will offer him the $6 million guarantee he earned for his assignment against Bradley. He could try to challenge Mayweather again, and could argue that when they fought Marquez was a blown-up Lightweight against a strong Welterweight. Time, or perhaps PED's, has transformed Marquez into a solid Welterweight.
Seanie Monaghan has the potential to be a regional draw on Arum PPV cards with his brawling style.
Lomachenko did impress in his "Pro Debut", even though he did have 5 fights in the World Series of Boxing. Looks like they will try and place him in there with Salido and eventually Rigondeaux.
The quality of the card, and the tactical nature of the main event, made the evening a mild disappointment.
