Marquez on that A-side meth

From my view of the fight I gather dinamita vs pac man was a pretty close fight. I personally feel that Marquez played it a bit defensive and should have stepped it up in the closing rounds just to put an exclamation point on win. Never understood the mentality of laying off the gas to cruise into a victory. Fights that come to mind are Trini vs Hoya. He should have won that damn fight, instead he just eased off the tempo like he won it already. With the controversy surrounding Marquez's strength and conditioning coach I wonder if Marquez was on the A-side meth to keep up with Pac. I'm just adding fuel to the fire but everyone was calling marquez old, past his prime, and that it would be impossible to defeat pac.
