He's too powerful for Jones, but Jones has better speed & stamina.
Problem with Jones is he's lost some power over the years, hasn't finished an opponent since the Cormier head kick.
He'd run around the Octagon trying to tire Ngannou out, but anytime he would get close enough to exchange he would suffer too much damage.
Jones doesn't have a string enough chin to take head shot from NGannou & wouldn't be able to take him down like he does every other 205er he faces.
It'd be a bad matchup for Bones IMO, the better fight would Jones vs Stipe.
