Man, if I'm Tan Tom and Sasso wants to go 157 AND Sasso can beat Gallagher, I'd have to consider that.
157 is probably the worst weight class right now in terms of depth. Austin O'Connor is coming off ACL surgery, and Sasso can likely beat many of the other top 157lb guys. He lost to Andonian last year 11-7, but I can't find the match.
He's likely 3rd at best at 149; he's not beating Yianni and took two Ls against Gomez last year.
