Rashard at 205 got by on his speed and the power-double. He was an ace at the double leg so he'd fake shots and hit guys when they thought he was going to grapple and grappled guys when they thought he was going to strike. But now that he's older he's lost his speed and athleticism.
I think he's still capable of blasting one on Kelly though because Kelly is an old man too. If Kelly was a better counter striker or if he had any distance weapons he could give Shad problems but old man Dan is more of a pressure stylist.
If Kelly is able to turn this fight into a clinch battle and walk Rashard down he could win in that fashion. To make it clinchy he needs to fight at arms length to shorten the distance.
I think if either guy wins it'll be by decision but if a finish materializes it'll be Shad GnP via full mount/back mount. All said, I ain't paying juice on brain damaged Shad face in 2017. I'm kinda considering the o2.5 but I'm not too sure.
PS I've always thought he was overrated. And funny story, back in the day, I bet on him to finish in the 2nd round w some ridiculous odds against Chuck Liddell.
