A small handful of GMs have built NBA championship teams. Red Auerbach, Jerry Krause, Pat Riley and Jerry West were GM for about half of all NBA's championships.
30 GMs compete each year for a championship and only 1 wins.
I have no idea how many GMs have never developed an NBA champion, but it is for sure that there have been hundreds.
Danny Ainge is in an elite class of GMs just for having built 1 champion. That doesn't give him lifetime tenure, but does afford him some respect (in my opinion) on the heels of putting together a team that in 5 years won a championship, lost in a Game 7 final, lost in a Game 7 ECF, and probably would have won another banner if not for a knee injury to Kevin Garnett.
This era has been officially over for a few days. Firing him would be asinine.
Disagree with his moves all you want, but give us a break and stop calling for his removal please. Just a request -- obviously you can do whatever you want.
