Celtics guard Payton Pritchard will become eligible for an extension before the season begins, but he’s in no rush to sign one. Pritchard said as much to Chris Forsberg on the Celtics Talk Podcast, as relayed by NBC Sports Boston’s Michael Hurley. It’s just not something I’m really looking at,” Pritchard said. We’ll talk, obviously, but we have a whole next year to talk about an extension. I feel like we have another year that we have to prove it,” Pritchard said.
