Think of Federer: he barely won another major after two year bust, and then USO '12, AO '13arrived and passed, with Federer's skills dulled in both. then, there was the Olympics, where he was soundly defeated. He is at the exact point of Sampras--more or less--and needs to consider his legacy.
But Roger continue to play and won Wimbledon, his 17th slams. He also reclaimed the #1 ranking and broke Sampras 286 weeks at #1. The more he play, the more he's adding more to his legacy, thus, distance himself more from the pack.
Tier1(goat): Federer; Tier 1.5: Laver, Gonzales, Sampras, Nadal, Borg;
Tier 2: Lendl, Connors, Rosewall, Tilden; Tier 2.5: McEnroe, Agassi
