No. 5 (tied) - Tony Guy, 74%, 1978-1982
Guy was a terrific player on some teams that weren't always among the best Kansas ever produced. In two of his seasons, the team finished around .500, while the other two resulted in 18 wins and 24 wins. They weren't dominant in conference and only made the NCAA Tournament once.
Guy, however, scored at least nine points every season and nearly 16 in the 1981-82 season in which they won 24 games. For his career, he scored 1,488 points, averaged 3.5 rebounds, 2.8 assists, and 1.4 steals.
From the line, he made 364 of his 492 attempts over his career. His best season from the line was 1979-80 season, when he went 84 out of 107, good for 78.5 percent.
Younger generations of Jayhawk fans' may not be familiar with Tony Guy, but he was an outstanding player, and he obviously was a very good free throw shooter.
