I voted no, clearly Bonds was a phenomenal player before steriod use. But I do understand the reasoning for considering the Asterick.
Take a look at his stats pre 2000 and post 2000 quite a remarable difference

Obviously Bonds has quite a remarkable improvement to his preformance since 2000, in which it would seem quite obvious Steriods have enhanced his natural abilities. Let alone the Fact that he should be on the down side of his career not the upswing at the age of 40.
It is foolish to think that steriods have not helped him get the single season record, nor more than likely the Career HR record. No doubt he has amazing Hand-eye coordination, why else would he be in the major leagues? Hitting a ball is a matter of hundreths of second for reaction time. Increased strenght allows one to get the back through the hitting area at a quicker rate, giving Bonds an opportunity to make better contact with the ball.
However, I voted no, because there are always going to be circumstances that could have impacted ones performance. He is a great athlete and nothing could take away from that, steroids or no steroids.
