BOSTON -- Ben Wallace has played professional basketball for quite a long time. In fact, he's played more games than any other undrafted free agent in his 15-year career and is currently the eighth oldest player (37 years, 159 days) in the NBA.
When you stick around that long, there's a reason for it: you're usually pretty good. Wallace definitely falls into that category. Wallace is a Detroit Pistons legend, to put it simply. A one-time NBA champion in 2004, Wallace became the ninth player in NBA history to amass 10,000 rebounds and 2,000 blocks and became the third Piston to record 7,000 boards in franchise history. Wallace is a four-time All-Star and a four-time NBA Defensive Player of the Year.
Certainly, his career has amounted to greatness, and he didn't see it coming.
