Some key notes from the article:
"Pierce took the tough love approach with Young from Day 1, opting to push him hard as a way of maximizing his celebrated talent. But Young, who had inspired so much hype during his time coming up in (and at) Oklahoma, often pushed back against Pierce’s style. John Collins could relate.
Pierce made a public comment two seasons ago about not running plays for Collins, and it rubbed the Hawks big man the wrong way. Collins went to Pierce about his issue with the statement, but Pierce, sources say, turned around and called Collins’ approach selfish in wanting to have a more defined role on the team. Over time, the residue from these types of situations remained."
"Cam Reddish was among those, sources said, who also had an issue with Pierce’s coaching. Sources said Reddish felt like he was being “picked on” behind the scenes when it came to mistakes the second-year player made. There are a few players on the Hawks’ roster who feel like Reddish’s potential is higher than anyone on the roster but that Pierce’s input was stunting his development."
"The lack of trust in Pierce, from numerous players, started in his first season. For The Athletic’s anonymous NBA player poll in April 2019, when one Hawks player was asked which coach in the NBA would you not want to play for, he responded with, “Are we allowed to say the one we play for?”
"The lack of faith in Pierce from the players quickly eroded last year, with several on the team feeling like they could not approach him without leaving the conversation feeling like they weren’t being heard. Because of that, players would turn to assistant coach Chris Jent in the hopes that he could be the one to relay any comments or concerns to Pierce on their behalf."
"During a league office Competition Committee call on Dec. 30, Pierce was among a couple of members who spoke out about the way certain players are able to draw fouls and, at times, bait officials into making foul calls. Multiple sources said he spoke about how he “hates” the shots Young takes at times and the fouls he’s able to draw on them. It was perceived as an interesting comment for several people on the call because Pierce’s star player has seemingly taken advantage of drawing fouls and getting to the foul line. But it was made in the broader picture of how players are drawing fouls by manipulating their bodies.
As far as on-court decisions go, players routinely criticized Pierce’s in-game management strategy over the past three seasons. One of the most notable moments of last season came in a December 2019 game in Miami. The Hawks led by six in the final minute when Pierce substituted Young out for DeAndre’ Bembry for defensive purposes. After Miami cut Atlanta’s lead down to three, Pierce failed to call a timeout to reinsert Young on offense. Bembry ended up getting his shot blocked, the Heat tied the game and it eventually went into overtime where the Hawks lost."
"Over the past few weeks, players started to wonder if Pierce had resigned to the inevitability of his situation and was going to go out his way. As the same story played out in end-of-game situations, sources say Hawks owner Ressler grew incensed with his team losing winnable games in the same manner."
