No. He won't. I'm sorry.
I hate to be disrespectful but no 5'7 lightweight is going to bring boxing back.
It have to be a Mike Tyson like or Muhammad Ali like Heavyweight.
Even a Riddick Bowe have 10x the chance of reigniting boxing in America than a Adrian Broner.
Heavyweights is the life line of American boxing, it is what it is.
If you have a 6'5 American right now with the skills of Bowe or Lewis, and he's 23? It's over.
But America don't.
