Did anyone watch Billy Joe Saunders vs David Lemieux? Saunders was absolutely brilliant. He looked like Tyson Fury at his peak, the skill, the movement, the speed, the art of not getting hit.
Golovkin or Canelo are in big trouble against Saunders if he reproduces that level of performance. His switch to trainer Dominic Ingle looks like it's finally brought out that talent that was always there.
The problem with Saunders is much like Fury though - at any time they can lose interest, lose their shape and their dedication.
