I'm wondering what kind of Sampras fan you are, if you didn't observe how he modified his style midway through his career. Sampras, in his younger days, was an ALL COURT player. He could rally anyone from the back of the court. For evidence see any of his early matches, not least his maiden UsOpen triumph.
Midway through his career, especially after Tim Gullikson's death, Pete adopted a HIGHLY aggressive style of play which was composed of shortening points, rushing to the net and taking more risks on serve. His basic aim was to litter up the stat sheet and go for a big shot as soon as possible. This was in part due to his illness (Thasselmia Minor) because of which he faced stamina issues, and didn't feel strong enough to rally for hours. He talks about this in his book too.
Anyway, after 1996, Pete pretty much gave up on the French Open and just focused on Wimbledon. He just went for winners on pretty much everything including low percentage shots such as service return winners, running forehand or DTL backhand. His ground game worsened as his fitness suffered too. But he was still able to hold the top spot because of his remarkable ability to play 1-2 tennis, his half-volleys, serve and the tremendous mental strength. I haven't see any better big match player than Pete. If there was someone you could bet your life upon, it was him.
