Media Paulo Costa visibly shaking on stage at UFC 318 press conference

[dipstickjimmy]

Costa is a big guy, look at home next to these welterweights.

The only other weight class he could go to is LHW.

Perry is a LW. Costa has a lot of muscle mass. You can add muscle, you can't really add to your frame. Make yourself taller or wider. Larger frame = Bigger. Costa could shed muscle mass and be a very effective MW but he chooses to carry too much weight. Its not like Luke Rockhold could have shed 3 inches in height to make WW. Hence why he was a MW. Costa is simply not a large MW. He is an overly muscled MW but not a large one.
