The fall of Adrien Broner didn't start with his lopsided loss to Marcos Maidana last December. I think we need to look all the way back to 2012 when he didn't come close to making weight for a defense of his 130-pound title against Vicente Escobedo.
Broner not only weighed in at 133.5 pounds for the first weigh-in, but he then also missed a second weight limit of 140 pounds on the morning of the fight, which cost him not only his title, but also a big chunk of the money he was set to earn.
It's not just missing weight; it's the lack of maturity that has penetrated every part of his game. It's his preparation, his attitude in the ring, the lack of respect he shows to other fighters and every other little aspect of what separates a good fighter from becoming a great fighter.
Broner bounced back with wins against Antonio DeMarco and Gavin Rees before a controversial win over Paulie Malignaggi to win the WBA world welterweight title. Broner deserved the victory, but it was closer than it should have been, which has continued to be a trend.
The split-decision win over an opponent he could have dominated should have woken up the young Broner. Of course you know the story by now and know that it wasn't the case.
Broner again didn't seem to prepare as hard as he could, took his opponent lightly and was rewarded by being knocked down twice at the hands of the always-focused Marcos Maidana.
Bruised and embarrassed, we didn't see Broner again until May when he fought on the undercard of the fight between Floyd Mayweather Jr. and Maidana.
Broner dropped down to 140 pounds—his ideal weight in my opinion—and also returned to fighting overmatched opponents when he faced Carlos Molina. "The Problem" won the fight easily, but then in true Broner fashion, he said something stupid afterwards that made everyone forget about the fight in the ring.
That might have actually been a good thing because the match was a dud like most of Broner's recent fights.
His fighting style is boring, he's unprofessional and the only top opponent he's faced destroyed him. For those reasons, Broner's stock is down.
