Pierce had to convince Garnett to waive no-trade clause, play for Brooklyn
Most people would probably be thinking, "Why not go to Brooklyn?" You get to live in New York City while playing for a championship title contender in a brand new arena. The decision for Garnett, however, was not so easy.
According to Barbara Barker of Newsday, Paul Pierce (who was also sent to Brooklyn in the blockbuster deal) had to spend over an hour on the phone with Garnett, convincing him to waive his no-trade clause and play for the Nets.
But it wasn't just reservations about leaving Boston that had Garnett wary of the trade. According to a separate report from Celtics reporter A. Sherrod Blakely, Garnett "absolutely" considered retirement this offseason. Garnett was likely most tempted to retire between the day that Doc Rivers was traded to the Los Angeles Clippers and day that the Celtics agreed to their deal with the Nets.
Pierce's efforts in that hour-plus phone conversation not only lured Garnett out of Boston, but also may have lured him out of retirement. Pierce's pitch likely included the fact that the Nets would be an instant title contender if the trade goes through, as well as the fact that Garnett would have two former teammates - Pierce and Jason Terry - to ease himself into a new situation.
After coming so close to retirement, it would be reasonable to wonder if most players would come back with the same fire and passion for the game as they had in the past. With Garnett, however, there is no reason for concern. Garnett is physically incapable of playing the game without putting winning above everything, and he'll never walk off the court without having left everything on the floor.
The fact that Garnett needed convincing to approve a trade to Brooklyn is simply an interesting story. It shouldn't foreshadow anything other than a very possible retirement next summer.
