Walker is a versatile big man who can play either forward spot. He is mostly used as a
small forward, where he establishes himself as a prolific scorer (career average 19.0 points per game) and deft rebounder, using his 6-foot-9 frame well (career average of 8.3 boards per game). He is also known as a capable passer, as 3.9 career assists per game prove. Walker is also known for his ability to shoot field goals, as he has taken 3771 three-point attempts in his career (as of September 2006), averaging about five per game, and made 1241 of them (.329). His all-around game earned him three All-Star call-ups so far (1998, 2002, 2003).
In spite of his consistent scoring and rebounding, Walker's game has been widely criticized over the years, mainly because of his questionable shot selection. By the
2000-01 campaign he had become the NBA's leader in three-point attempts, although .329 was not a remarkable three-point-shot average. Walker's penchant for shooting three-pointers is thought to stem from his playing for coaches
Rick Pitino and
Jim O'Brien, whose offensive techniques of shooting high volumes of three-pointers became known as the "Bombs Away Offense" among Celtics fans. However, Walker has improved this in his days with the Miami Heat, shooting 43.3% from the field, profiting from playing third fiddle to teammates
Shaquille O'Neal and
Dwyane Wade who often draw double-teams, so Walker frequently has wide-open shots.
Walker has been criticized for his lack of effort in conditioning. In the
2006-07 NBA season, Heat coach
Pat Riley suspended Walker for four games for failing to meet conditioning standards. In the 2007-08 preseason, Walker reportedly arrived at camp at an estimated 262 pounds with 15 percent body fat, well above his listed playing weight, irritating Riley enough to call Walker out in public about the issue. Riley suggested that Walker is in good enough condition to only play 15-20 minutes per game, and will not be almost certainly not be starting. When asked why Riley did not provide a mandatory conditioning session over the preseason, he responded; "You can't force these guys to do anything during the summer, because they can call the players' association and then the players' association calls me, and they fine me." Walker was traded to the Timberwolves a few days later, although Riley said it was nothing personal and more of a personnel decision. Currently, he is one of 6 ex-Celtics players on the Wolves' roster, with the other 5 being
Al Jefferson, Gerald Green, Theo Ratliff, Ryan Gomes and
Sebastian Telfair.
