MILWAUKEE — Dick Garrett is not the type of person who draws attention to himself. Co-workers at Bucks games have gone entire seasons without realizing his special connection to the team. Even some of the regulars who sit in the section of the arena where he works security are oblivious.

So when Peter Feigin became the team president in 2014, he only got to know Garrett in his role as one of the franchise’s more beloved employees, largely because Garrett never talked much about himself. But a few months into Feigin’s tenure, the Bucks organized a dinner for former players, and Garrett showed up.

“Dick,” Feigin recalled asking him, “what are you doing here?”

At the time, Feigin was embarrassed. Perhaps he should have known that Garrett played for the Bucks the last time they went to the N.B.A. finals, in 1974. Or that he was once named to the N.B.A.’s All-Rookie team with the Los Angeles Lakers. Or that he had an eventful five-year career.

But Feigin said he also came to realize that it was entirely in character for Garrett to keep his story quiet. Whenever people ask him about his days in the N.B.A., Garrett usually says something like, “Oh, I used to play some ball.” He is more likely to talk about his family, or his golf game, or the 28 years he spent selling beer for Miller.
