Nope.
Jones is master of using his size and reach. Even after last night, I still think Alex is the only man who can possibly beat Jones. Jones doesn't have the KO power of Rumble or even Cormier, so Alex (as we saw when they fought) wasn't afraid of getting up close and personal with Jones, and one man left the cage being held upright, with his face looking a mess that night, and it wasn't Alex.
Rumble is basically Glover against Jones, a punchers chance. MMA is such a weird, amazing sport - styles truly make fights. You may not be able to beat fighter a), but if you have the physical size and tools, you can give the champion the toughest fight he;s had in his entire life.
Rumble will get submitted within 3 rounds, IMO. I'll be rooting hard for Rumble, but he won't be able to land those shots against a guy who's a master of keeping distance. He doesn't have KO power, but Jones can take advantage and wear down a tired guy...Rumble gets tired, as we've seen in the past. Alex doesn't. It's an odd situation but the man who got destroyed this weekend is still the ONLY man who can give Jones a true test, due to physical attributes and cardio alone.
