Im going to start by saying Jones is right now almost unbeatable. But i think there are a couple fighters out there that could beat him. 1. Alexander Gustafsson. what needs to be said he gave bones a war the first time around and has the size and tools to beat him. 2. Cain Velasquez. The plan cormier had against Jones was good but imagine Jones vs Velasquez. It would be pretty much the same fight with cain pushing the pace but cain would not get tired like cormier. 3.Fabricio Werdum. His ground game will probally make jones think twice about wrestling him. Will be a stand up war. 4.Chris Weidman. This would be a good superfight. Weidmans wrestling and standup improves every fight. These are the only fighters i can see that can beat Jon Jones. Please comment about my list and come up with your own list of fighters that could beat Jones.
