I don't disagree, but that's not what you asked either. Money and winning are great, sure, but many players before Dejounte have harshly discovered that there's more to life than that. Fan love and having a place to call Home are important, too, and DJ's career could quite easily turn around into him not having that in the future.
Take Durant, for example, who doesn't even like the one team that will probably retire his jersey (Dubs) and has many times more haters than fans across all 30 teams. Or the classic "they don't love you like that!" bit between Pierce and Draymond. Or etcetera. Once the years start adding up and he takes a long, hard look at his career - I think Dejounte very well could come to miss the Spurs and cherish the years he spent in the "family" and being "the dog" of the young squad.
...or maybe he three-peats with Trae in ATL and has a home there forever, who knows. I was just making the point.
