Oklahoma State Basketball: Best and worst NBA Draft picks in Cowboys history

5.  Brooks Thompson

The 6-4 point guard turned back-to-back All-Big Eight selections in his two seasons in Stillwater, where he averaged 15.8 points and 5.4 assists, and 2.7 steals, into the 27th overall pick in the 1994 draft. Thompson, who had a nice left-handed shooting stroke, compiled 4.5 points and nearly one-3-pointer per game on 40.9% shooting from the field and 37.6% from beyond the arc over 168 games spanning four seasons. He played for the Orlando Magic, Denver Nuggets, New York Knicks. Phoenix Suns and Utah Jazz. Following his playing days, Thompson spent 10 seasons as the head coach at UTSA before passing away at the age of 45 due to double organ failure.

4. Richard Dumas

Dumas was plagued by drug problems throughout his collegiate and short professional career. Still, the No. 46 overall selection in the 1991 draft demonstrated his scoring prowess. He averaged 10.6 points for his career, which included putting up 15.8 points a game over 48 appearances during his rookie season (1992-93). The second-team all-rookie selection played 102 career games for Phoenix and Philadelphia.

3. Desmond Mason

The No. 17 overall pick in the 2000 draft had a solid 10-year NBA career where he averaged 12.1 points along with 4.5 rebounds while shooting 44.9% shooting from the field. Mason, a two-way wing, was a three-time All-Big 8 selection which included earning a first-team nod in 1999-00 when he compiled 18.0 points and 6.6 boards. D-Mase, one of his nicknames, played for Seattle, Milwaukee, New Orleans, Oklahoma City, and Sacramento.

2. Tony Allen

Allen, a notoriously physical and tough defender, became a six-time all- NBA defensive selection and an NBA champion in his 14-year career. The 25th overall pick in the 2004 draft averaged  8.1 points, 3.5 rebounds, and 1.4 steals during his tenure while playing for Boston, Memphis, and New Orleans.

1. Marcus Smart

Smart is the only former Cowboy still in the league. The former second-team all-American selection is a tough-as-nails defender who goes all-out when on the floor. The two-time all-defensive first-team choice is coming off a career season this past year, compiling 13.1 points along with 5.7 dimes and 3.5 rebounds, as well as 1.5 steals.
