He spent his entire professional career playing for the
Indiana Pacers. With the Pacers, Smits originally backed up
Steve Stipanovich, but when Stipanovich suffered a career-ending injury, Smits ended up starting 71 games in his rookie year, averaging 11.7 points and 6.1 rebounds per game and earning All-Rookie First Team honors. Smits continued to average double-digit point totals in every year of his career, but it wasn't until the
1993–94 NBA season that Smits really came into his own as a team leader. Throughout the Pacers' playoff runs in the mid and late 1990s, Smits was considered the number two player, behind
Reggie Miller, on the deeply talented Pacers. Smits' highest point-per-game average was in
1995–96 when he averaged 18.5 points per game. That season, on December 10, Smits scored a career-high 44 points during a 111–104 win over
the Los Angeles Clippers. He was relatively modest by NBA "superstar" standards, but the Dutchman endeared himself to Pacers fans with outstanding playoff performances, most notably in Game 4 of the 1995 Eastern Conference Finals, where he made a buzzer-beating shot to tie the series. Smits was named to the
Eastern Conference All-Star Team in 1998, delivering ten points, seven rebounds and four assists, including a behind-the-back pass to
New Jersey Nets forward
Jayson Williams who followed immediately with a slam dunk. Smits developed nerve damage in his feet from wearing tight shoes as a teenager. To help recover during the off-season, he spent time relaxing at his summer retreat in
Walton, New York, where he was a regular attendee of The Afton Fair. Foot problems hobbled Smits for the majority of his career, and he retired at the conclusion of the Pacers'
1999–2000 season, after Indiana was defeated by
the Los Angeles Lakers in the
NBA Finals 4 games to 2. on Alumni Day.After four surgeries to repair nerve damage to his feet, Smits underwent intensive back surgery in November 2009 to correct cracks in one joint that link his vertebrae. Smits has also undergone arthroscopic surgery on his left knee and had bone chips removed from his left ankle. Smits was selected to the Pacers' 40th Anniversary Team, chosen by the fans. He ended up with the fourth most votes, trailing only
Reggie Miller,
Mel Daniels and
Jermaine O'Neal. ==National team career==
