2. Steve Nash
Though the argument that Vaughn was somewhat "carried" by having the likes of Kevin Durant and Kyrie Irving in tow could certainly apply to the likes of Steve Nash, at least he was able to achieve a level of success that is still unmatched by anyone else on this list during the time he spent holding the clipboard on the sidelines.
Without any prior head coaching experience, the Hall of Fame point guard was thrust into the tough position of trying to establish this Nets team as a legitimate title threat, and, in many ways, he accomplished such a feat.
While they may not have wound up bringing home the highly coveted Larry O'Brien Trophy, Brooklyn finished as a top-seven seed each year and came within literal inches of advancing to their first Eastern Conference Finals appearance since 2003 during his first season with the organization.
It's hard to judge Nash on his X's and O's abilities considering he essentially let his stars serve as the coaches on the court, but during his two full seasons, Brooklyn ranked as a top-10 offensive unit, even registering as the best offensive team in the league back in 2020-21, and ranked within the top-12 in pace, a statistic that the headman likely had an impact on considering his "seven seconds of less" brand of mentality from his playing days.
Had Durant's foot not been touching the three-point line during the closing seconds of Game 7 in the 2021 semifinals against the Bucks, perhaps Nash's reputation would be a bit different than it is right now.
On top of this, perhaps he'd still be the one running the show for the Nets.
Regardless of these "what ifs," it shouldn't be a surprise to anyone that he finds himself landing in the top-two on this particular rankings list.
