Pete played his entire career with Thalysemia (did I spell that right? I think not), a blood condition that can create fatigue and lack of conditioning. The fact that he was able to achieve what he did under those circumstances is pretty awe-inspiring to me.
As for his match record, Pete said many, many, many times that he was mostly concerned with Slams and maintaining his #1 ranking, not necessarily racking up titles (which might possibly be one of the reasons Andre has more Masters titles). He did what he needed to do to achieve those two goals. What made Pete great is a combination of the way he played the game and his results, not just his results.
Would have been easier for me to respect your argument a little bit more, Vogus, if you had left out the apparently derisive nickname. Your personal problem with Mr Sampras detracts from your argument (to me anyway).
