Marquez got the W but is he clean?

Time to post. First off, Congrats to Marquez for that earth shattering punch. You deserve that w. In my early posts before this fight ever happened I always said roided or not, Marquez will be given credit if he wins. That said, watching the fight. He sacrificed some speed for power. He wasn't throwing combos, His game plan was to get one in and end the fight. Ala Mike Tyson. The thing is he isn't even a heavy weight to think in that aspect but he did. He know he has the 1 punch power to end a fight. That for me is what's questionable. He mustered power at an age were he is turning 40. When in his previous 3 fights with Pac. He hit pac solidly so many time in these 3 fights and Pac never got knocked down. That for me is telling. He isn't at a prime to find new power in himself. He was @ almost 40. Only logical explanation is roids. As I said props to him for winning but he did win with roids. To strong for a man not known for that power. Pac in the other hand was blitzing boxers before, and was accused of roiding as well, but the difference with Pac is, he is a known puncher and he was blitzing people in his prime not when he was at the end of his career. It was his prime self and his physical attributes that made him a typhoon. That's the difference. If you suspect pac is roiding what more with a 40 year old man who looked like he can throw like a heavyweight. I know some would say, hey that was a perfectly timed shot anyone will go down with that. But look at the previous 3 fights. Marquez hit Pac cleanly so many times but Pac never went down. Just sayng it really is suspecting to see where the hell did that power come from. Roids?
