It's dumb saying he's "afraid" of him. These guys fight in a cage for a living.
But I can guarantee he doesn’t like the matchup. A younger, much bigger and definitely faster guy with KO power and at least a fairly good grappling base isn't a fight Jon is dying for.
It's interesting, people talk about Jones fight IQ maybe his biggest asset (and I mostly agree) but can't wrap their brain around him seeing this guy and saying "Nah...I don't need that problem at 38 as I'm one foot out the door. No thanks. Give me the smaller guy that's a bigger name who has no grappling abilities please."
I've said this in other threads: First, what some haters might say afterwords if Jones wins ("Tom was never that good!") shouldn't determine title fights. Ever. BUT, Jones has no obligation to fight Tom IF Jon is willing to vacate the belt. He can then retire or fight Alex or whoever.
The odd thing is, why would Jon or his fans care what some people might Tweet about Tom if Jon beats him...but somehow DON'T care about the fact those same people think he's ducking Tom now? Either care about those people's opinions or don't, but don't pick and choose when they matter.
