32 players you forgot were once NBA All-Stars

13) Antoine Walker

Three-time NBA all-star Antoine Walker spent the majority of his career with the Boston Celtics and emerged as one of the most prolific stretch-fours of the 1900s and 2000s. Walker developed a reputation as a bomber, launching threes whenever he got a chance to.

He would have been right at home in today's NBA, though he wasn't all that efficient. During three of his best seasons, he attempted 7.6 threes per game—high even for today's NBA and outlandishly so for the early 2000s—and shot just 34.5% from deep.

That was above average for that era but he shot poorly inside the arc and from the free-throw line. To his credit, he averaged a terrific 21.9 points, 8.3 rebounds, and 5.1 assists from 2000-01 to 2002-03, proving that he wasn't just a bomber.

Even so, he was traded to Dallas for an underwhelming package despite being a 3-time all-star and still in his 20s at the time. He failed to put up big numbers playing alongside Dirk Nowitzki and was traded to Atlanta, where weight and injury issues quickly resulted in him becoming more of a role player.

Fortunately for him, he later signed with the Miami Heat and won a championship in 2006, though he was out of the NBA by his early 30s. Walker perhaps played in the wrong era and could have thrived in the more 3-point-happy NBA of today but he still managed to make three all-star teams and averaged more than 20 points per game four times. Few NBA players can say the same.
