Canelo not a true MW doesn't count in my book. Andy Lee is the Jacobs backup, Eubank JR was over his dad, and well yeah Quillin counts
He's Lineal Champion of the division though...it's not right to drag out a fight vs the best opponent in your division for so long.
I said this same thing about Floyd vs Manny.
Nobody wants to wait years to see the best 2 fighters in the same division face off.
