If you had to narrow it down to one what-if per franchise, which one makes the cut?

I’ll give examples using the team I support (the Celtics):

Injuries - KG’s injury in 2009. The Celtics had a scorching start to the season, but lost in 7 to the Magic. KG’s absence let Dwight loose on the boards, & the next year when they did make the finals the Big Ticket had clearly lost a step.

Deaths - Len Bias in 1986. Red Auerbach had drafted a potentially transcendent player to back-up the greatest frontcourt in the history of professional basketball. Instead, a cocaine overdose killed him hours after being drafted No. 2.

Draft Picks - Kedrick Brown in 2001. Know who the Celtics had wanted to draft? Tony Parker. Unfortunately then-GM Chris Wallace was overruled by Celtics patriarch Red Auerbach.

Suspensions - Ime Udoka in 2022. Just months after taking the Celtics to the NBA finals, the former Spurs assistant was suspended for inappopriate relations with a female employee.

Made/missed shots - Artest’s 3-pointer in 2010. I will always believe we’d have stolen that game if Ron Artest Metta World Peace doesn’t drive that dagger through our hearts.
