Career Journey
Dallas Mavericks
1983-1994
Derek Harper was the kind of point guard whose value never fully showed up in a box score. A first-round pick out of Illinois in 1983, he spent 16 NBA seasons — the first ten in Dallas — and built his reputation on relentless on-ball defense, earning All-Defensive Second Team honors in 1987 and 1990. He paired that pressure with steady, low-turnover playmaking and a dependable pull-up jumper, steering the Mavericks through their early playoff runs. Harper remains the franchise's all-time leader in both assists and steals, and Dallas retired his No. 12 in 2018. He is often cited as one of the best guards never selected to an All-Star team — a durable two-way lead guard who later moved into the Mavericks' broadcast booth.
