You may be right, but I think it depends on how he feels fighting at that weight. If he, for example, booked a fight against the champ and went on an dominated him then he may not feel the need to bulk up and can fight in both divisions. If he fights at welterweight and struggles in the grappling then he may feel the need to add some muscle. I would really like to see him fight at 170. I honestly thinks he beats Leon easily and can't think of anyone other than Shavkat Rakhmonov or Jack Della Maddalena that would give him a good fight.
