I think what Jackson is getting at is that Sonnen has been training with Henderson, so he knows what game plan Hendo would use, and is more prepared for JBJ than some of you think.
I don't think so. Everybody knows what gameplan Sonnen is going to use against them, it's a matter of stopping him. Hendo would've stood with him in hopes of landing that overhand while Sonnen would have pressured him from the go and try to take him down. He didn't train for a double leg quite like Chael has.
It would've been a whole different fight for Jones.
