The Burns fight is an interesting one.
Broner hasn't faced anyone with the pure boxing pedigree that Burns has either. Burns has a great jab, solid movement, and he throws power punches (even if they don't have crushing power, they score) upstairs and downstairs really well. He's taken down Rocky Martinez, Kevin Mitchell and Michael Katsidis on the world class level, none of which have the skills set of Broner. But, outside of Floyd, who the hell does have the style and set Broner does? Good luck finding that.
I think it'd be a very competitive fight, honestly. I don't see Burns winning it, but it will answer questions on Broner as to how he'll fair with a pure boxer and whether Broner can go a full 12 rounds with a guy who is always in great shape.
