I think this is conors best move. Take all of 2018 to pack on lean muscle mass to properly fight at 170, then fight for the 170 strap. I think Conor beats toney if he wants. But for Conor it's all about doing things no one has done. Already only 2 weight world champion at same time. Holds all PPV records. Only MMA fighter to box against a GOAT boxer and be competitve. Now if he beats Woodley for the 170 belt, Wich is a possibility judging by Woodleys last 2 fights where he's scared to engage, he will be the only UFC fighter to hold belts in 3 different weight classes. He should then retire with over 100 mill made career wise. And the haters will cry forever after that until the rest of time " her der, Conor never defended a belt".
