Rich Franklin was definitely big for a MW. Actually he only fough there 10 times and often fought cathweight bouts because he had problems making weight and he was a posterboy for the UFC so they allowed them to do so. He was also ahead of his time in terms of nutrition and conditioning. Luke Rockhold would manhandle Franklin with his grappling. I mean, Okami and Lutter put Rich in very bad positions. Not only took him down but also mounted him with not much difficulty. Rockhold would rape him. Franklin vs Bisping would be an interesting battle. I actually favour Rich in that match-up but Bisping was a better deffensive grappler.
