Jones is 100x way more skills than every HW fighters in the UFC.
The only person I see gve Jones probably is Cain because of his dirty boxing and wrestling and pace.
JDS? I see Jones picking JDS by strikes. I don't think JDS will take Jones down.
So by striking, Jones probably pick JDS apart because he's too slow for Jones. Jones would poke JDS and kick his knees over and over like Rampage and JDS won't even be able to land a hard hit on Jones.
Cain on the other hand will push Jones and clinch Jones to the cage and could take JOnes down, but remember, Jones ain't so slow, he's 100x more skills than every HW even mre skills than Cain.
So you imagine a 240 pounds Jones vs Cain, you know Cain will have big problem too.
Jones might even wreck and finish Cain by sub or TKO since Cain rarely have a chin.
Remember Kongo rock Cain badly every round and Cain have his wrestlingt o save him from Kongo.
On the other hand, Jones have the wrestling to deflect Cain wrestling too.
It's Cain pace and dirty boxing that will give Jones problem but since jOnes have a iron chin, hard for Cain to win by TKO/KO.
Cain might win by decision.
Stop imagining a 205 Jones vs Cain or JDS, even at 205, Jones still weight around 220 pounds during fight night.
Imagine a 240 Jones and 245 pounds Jones fight night, he would be a dangerous opponent for the HW division.
Look at Jones brothers and tell me. His younger bro look freaking huge, like 6'6" 270 to 280 pounds.
