At 140 Hatton's quick feet would make this interesting...but I think Laguna's overall speed would make the difference for a decision win in a fun fight.
Hatton could never make 135. But Laguna was SEVERAL levels better than Hatton and would slice him to shreds.
Laguna clearly, Hatton would have to nail him to have a chance and I can't see him every catching up to the very fast Ismael.
Hattons best chance is to slow Laguna down with body shots and try to maul him like he did KT. I can't see that happening as Laguna had quick elusive feet and fantastic hands. As someone said above Hatton gets sliced up.
