Jones is tall and athletic as hell. Wait til Jones hits 28-30 years old and you'll see him move up (if not before then due to lack of comp in LHW). Jones is a natural HW. Quit trying to act otherwise. Silva is a natural MW. He's talented enough to do well at LHW but he's a MW.
And the only WW comparable to GSP's build is Thiago Alves and that dude has serious issues making weight. Btw GSP is listed* at 5'11".
I'm saying though! Jones has height/reach/youth and athleticism on his side against Silva. The two aren't at relative stages in their lives, physical builds or careers. That Silva v. GSP fight makes much more sense.
