Sami was determined to drop weight, similar to Hero but Steen just doesn't seem all that bother. Brings it up in his shoot with Davey. If he did drop weight, I don't know why WWE would sign him anyway? He would of been good pre-PG are.
From what I've been hearing lately, post-Davey shoot (so, in The Kevin Steen Show with Michael Elgin and his second Art of Wrestling podcast episode), he's finally committed to getting into shape.
