Eh I think McCray would be good at 185. Bryant should definately drop to 70. He reminds me Josh Haynes from Season 3.
He's bulky with a good amount of fat, and short arms(70 inch or so). Mccourt who is 3 inches shorter has a 6 inch reach advantage arm-wise. He could stay at 185, but I think 170 would suit him better if he can make the cut.
