Update: Jared Weiss of The Athletic:
Marc Stein of The New York Times:
Kelly Olynyk ($13,067,885 salary next season, $13,598,243 player option the following season) is an expensive stretch big, but he’s cheaper than Dragic.
Derrick Jones Jr. ($1,645,357 salary next season) is an athletic energy forward.
I wouldn’t take that combination without a sweetener, and maybe the Mavericks got one. Or maybe Dallas just liked Olynyk and Jones that much.
