NBA Coach of the Year Odds: Brown Conquers with Kings

Previous COY betting action

1/17/2023: Joe Mazzulla still leads the field, with Boston now righting the ship after a brief skid, winner of seven straight and now 4.5 games clear of second-place Brooklyn in the East. The Celtics still own the league's best net rating, and Mazzulla getting a quick response from his troops after their deflating blowout loss to OKC has helped his case, keeping Boston focused through the January doldrums.
Speaking of Brooklyn, the Nets' charge up the East standings was halted by Kevin Durant's recent injury — likewise stalled, for now, has been coach Jacque Vaughn's bid to challenge Mazzulla for top COY odds, still a close second at +320.
1/3/2023: Joe Mazzulla continues to pace the COY field with just under half of the regular season played. Despite some stumbles to close the 2023 calendar year, the Celtics still own the league's best record and net rating, which is all the more impressive given the mere weeks Mazzulla had to prepare for an NBA head coaching role. Elsewhere, the biggest mover on the board has been the Nets' Jacque Vaughn, who also took over on short notice, following Steve Nash's prompt dismissal. The Nets have won 12 straight and have the entire league taking notice, which is huge of Vaughn's narrative after a disastrous start in Brooklyn.
12/6/2022: Mazzulla's managed to perhaps even exceed the Boston Celtics' preseason expectations, steering them to the league's best record with their offense, surprisingly, easily No. 1 in the NBA. The Celtics are inching ahead of the field as NBA championship odds favorites, and look to welcome back defensive lynchpin Robert Williams III soon. Elsewhere, Mike Brown and Rick Carlisle continue to keep their names in the discussion with the stunning success of the Kings and Pacers, while Willie Green also vaults near the top of the board on the heels of the Pelicans' four-game win streak, currently second in the West at 15-8. 11/22/2022: The Celtics are streaking and Mazzulla's preseason narrative is only strengthening his case as a Coach of the Year candidate. With Boston atop the NBA at 13-4, its surprise coach has overtaken the top COY odds spot, with several veterans surging behind him. 
With the Pacers and Kings surprisingly in the thick of each conference's playoff race, Rick Carlisle (+1,000) and Mike Brown (+1,200) have both seen their odds shorten hugely in the past week, now among the second tier of contenders chasing Mazzulla and his former bench mate — Utah's Will Hardy (+400).
11/9/2022: The Jazz are unfathomably first in the West at 9-3, and rookie head coach Will Hardy deserves lots of the credit considering his team came into the season with zero identity, little if any continuity, and a fairly transparent mandate to tank. Hardy sat as last week's new odds leader, but his price has only shortened with the Jazz's continued success.
Elsewhere, it was widely rumored last week that Ime Udoka's hiring by the Nets was imminent, but the continued PR fallout from the Kyrie Irving antisemitism debacle has forced Brooklyn to pump the brakes and instead name interim coach Jacque Vaughn as their new bench boss, installed at +2,000.
11/2/2022: With the Jazz surging against every preseason expectation, Will Hardy leapfrogged to the top of the COY odds board (+850). But his odds movement lurked under the headlines coming out of Brooklyn that suspended Celtics head coach Ime Udoka would be hired by the Nets in the wake of Steve Nash's firing. The preseason Coach of the Year odds leader thus re-entered the race at +1,000.
