OKC Thunder: Mark Daigneault Among Longest Tenured NBA Coaches

The Oklahoma City Thunder are on top of the NBA world right now.

After capturing the first championship in team history, the OKC Thunder seems poised to defend its title this season, even in the midst of the first-ever parity era in league history.

Though, it wasn't long ago that the Thunder hired head coach Mark Daigneault who brought the Bricktown through a rebuild and now has paced the sidelines for back-to-back No. 1 seeds in the Western Conference and the franchise's first title.

After starting his career with two 20-something win seasons, Daigneault is now an over .500 winning percentage coach that has a Larry O'Brien and Coach of the Year award to his name.

It is no surprise that Daigneault is viewed as one of the best coaches in the NBA and has a job in Bricktown for as long as he wants it.

Hoops Trade Rumors writer Luke Adams compiled a list of the longest tenured coaches around the NBA.

What is interesting about this list is that if you go by offseason, Daigneault would tie for the third longest tenured coach in the NBA. That offseason was strange coming out of the pandemic disrupted 2019-20 campaign. The Thunder agreed to part with Billy Donovan who headed for the Windy City and elevated its former G League coach to the varsity job just weeks before the next season began.
