Jones with the same skillset but at 5'9" wouldnt be as successful.
His range and reach helps alot.
DC closed the range this time around and, until he got caught, was fighting a good fight.
When fighting people like Jones, with so much reach advantage and his annoying proclivity to poke people out, getting his attention to his legs is primordial.
If someone can develop a solid leg game against him, really fuck up his lower legs, I can see him getting knocked the fuck out.
