Danny Ainge.
For those calling me crazy, just think about the career DA has had associated with sport and the stories he could tell. Danny growing up as a two sport guy, actually playing in the MLB, being picked by Boston, stories about Red, Bird, McHale ect, going against Thomas, Magic, Kareem, Hakeem, Jordan, Pippen, coaching the Suns and all the wheeling and dealing as Boston's GM of course as I can imagine how many great players were so close to being signed, traded or drafted.
I know people would say Jordan but I feel that there has been so many Jordan stories already and Danny has been around and see it all in the NBA for essentially 36 continuous years.
