When has Magny ever executed a kick heavy game plan effectively? His punches are loopy straights and crosses. His takedowns are not great. He's definitely rangey with solid cardio.
Lawler VS RDA was Robbie fuckin his knee(s?) real good, yet hanging in there. Still threw and landed some bombs on RDA. It was a textbook RDA performance though. Also, mma math here totally, but RDA is one of the biggest talents Magny has fought, and RDA smoked em (on the ground, but he couldn't do that to Lawler - maybe there's a connection somewhere in these fights, I don't know).
I think at the odds Robbie is a good play. Lombard was real close to finishing Magny and Lawler could fight similarly. In his heyday, Lawler could execute the same ass whooping that Ponz laid on Magny too.
