Has any recent series had a better success rate from its supporting cast than Parks and Rec?

Most went from supporting roles in Parks and Rec to leading their own successful projects.

Aziz Ansari - went on to lead his own series, win Emmy award

Nick Offerman - Emmy nominated host of his own series, Emmy winner for The Last Of Us, multiple high profile film roles

Aubrey Plaza - Emmy nominee for The White Lotus, several successful leading film roles

Chris Pratt - lead role in popular Marvel franchise, Jurassic World, voice of Super Mario and Garfield

Adam Scott - Emmy-nominated lead in Severance and other major TV roles in The Good Place and Big Little Lies

Retta - lead role in successful series Good Girls

Rashida Jones - lead role in new series Smiley, writer for Toy Story 4 and Black Mirror, several major guest roles

Rob Lowe - was successful before Parks and Rec, but still, currently a lead in his own series

Ben Schwartz - lead voice role in Sonic the Hedgehog films.

Contrast this with The Office, where all but John Krasinski, Mindy Kaling and Phyllis Smith have pretty much fallen off the map.
