It would be nice to ee film of Burley to see if he had any style bogies, whn under pressure that Bad Bennie might of been able to Exploit, however this does not seem to be the case ( unless the old Jimmy Jacobs Collecton had something ? ) From what i understand Charley was very fluent, could box off the back foot, cold throw combinations and was very well balanced, I suspect most will conclude that if Gregory could push Bennie Close, Hart grab a Draw, and Valdez go 3-0 with Bennie, then the much heralded Charley would have been able to matador Bennie for a clear points Decision.
Well just based on the limited footage I have seen of Burley I would have to say Burley by UD. Burley looked like he had that perfect shoulder roll defense. Precise punching with power. I think he would pick apart Briscoe.
