Comparing the Dallas Mavericks to where they were following the Covid-19 pandemic to now, the team has obviously undergone drastic changes, as nobody thought the Mavericks would trade Luka Doncic before he fully hit his prime back in 2020. The Mavericks were under a completely different management, coaching staff, and owner back then as well, as it's clear Dallas was far more risk-averse when it came to making transactions back then.
One of ex-Mavericks general manager Donnie Nelson's final transactions during his tenure in Dallas was selecting Josh Green 18th overall in the 2020 NBA Draft, and while Green was lauded as a stellar selection back then, the Mavericks likely regret the fact that the old regime took Green considering the limited amount of first-round draft picks Dallas is projected to have this decade.
