Broner has checked out of boxing a while ago.
A lot of his career he's been out worked by his opponents early as that is his style but after losing the first time it seems he's there for the pay day fighting a super lazy style with some dirty tactics (low blows).
Broner cares more about outside of the ring activities then boxing and some of those have obviously got him in trouble with the law.
Edit: Ok so Broner finally started fighting around the 7th round or so making this more entertaining.
