Colby is washed imo. He didn't look good in the title fights he was granted so I don't have a lot of confidence in him. Joaquin Buckley is a tough guy so I think Colby has his work cut out for him but if he can win the grappling exchanges maybe he can win the fight. I just think he's overhyped by the UFC because they really wanted him to be champion and he's fallen short despite numerous shots at the title.
