My brain says Frankie wins this with the wrestling being neutralized and him popping Chad with shots over the course of 5 rounds.
But I have a feeling Chad will eventually hurt Edgar and get a tko. Edgar's footwork is ever-improving but he's still very hittable and with the reach being so close, he's going to have to get into Chad's space in order to land. And while he was able to move in and out cleanly with Faber, I believe Chad to have the better footwork and standup between the two.
I'm just fucking excited really.
