Silva would probably play evasive and exhaust Jones until round 4/5 and then choke him. On the other hand, Jones could use his power and extra reach to go for KO.
Really? Jones has shown more than decent cardio in his fights so far. He has gone past the 3rd round thrice now and he hasn't shown terrible cardio issues.
And Jones standing with Silva...? He has looked good standing against the likes of Rampage, Shogun, and Vitor, I'd give you that. However, against Silva? Even with his longer reach I think Jones would not contemplate striking with Anderson freakin' Silva. He does not really have the power to knockout iron-jawed Silva, and striking with Silva for 25minutes is insane. The only way Jones is going to win is taking Silva to the GnPing to a victory, yet Silva is no slouch of his back either.
All these talk is useless though. Dana won't be able to force Silva to move up a weight class and fight the light heavyweight champion, and Silva has stated explicitly he wants to stay at middleweight. Furthermore, why would Dana put Silva vs Jones as an exhibition match...
? If the fight is going to happen the UFC is going to squeeze dry the money potential in that fight.
