Weidman is a big MW, he is 6'2, has a 78 inch reach and would have no problem moving up to LHW. He stated himself that he is usually around 203 and would move up if the UFC and fans wanted it but he wanted to be the MW champion first.
I agree with others that it is early to have a Weidman vs Jones fight but I'd love to see it down the road.
There are plenty of pictures and videos of him out there when he wasn't in camp and he gets HUGE.
check him out next to Bader
