I think Jones' wrestling is enough to nullify a TD. Hell, Jones has tooled very accomplished wrestlers. Jones may not have one shot KO power, but he'll beat you to a pulp until you quit regardless of how tough you are (see Shogun).
Jones hasn't fought anyone near the level of wrestling that Cormier has.
Yea, he beat Shogun down. But he went 5 rounds with Rashad, beat him easily, but it wasn't a beat down. Same goes for Rampage, he easily out-struck him but it wasn't a beat down He wore him out and then choked him out. He didn't beat Machida down. He landed like 1 or 2 good strikes. Then caught him with the choke. The guys he has beat down besides Shogun were guys who were caught underneath his elbows.
