To be clear, I don't think anyone comes close to O'Toole, Haines included.
Hell, I don't know if Haines gets the nod over Facundo at this point. I know it was a recently ~157lb Haines vs a Facundo that had acclimated to ~163lbs for the MFS season, but Facundo didn't beat him with Parterre.
Using the season to bulk in to 174lbs on a Redshirt might be what the doctor ordered for him, as it were.
