I believe Diaz has improved since the St Cruze fight. logic say the guy worked his butt off and got tougher. He is limited in ability but makes up for it by just having some tenacity and good work ethic.And the fact that he had less wars with elite fighters means he is fresh.It's not enough to topple Manny though. Casa on the other hand has progressively been diminishin It is clear by watchin his fight with Katsidis and he always had a weak chin btw..
