The Dallas Cowboys have a proud history but like every other NFL team, they have had some draft picks that haven't worked out.

Let's look at the five biggest NFL draft busts in Cowboys history.

5. David LeFleur (1997, Round 1, Pick 22)

The Cowboys needed a replacement for tight end Jay Novacek, so they brought in David LeFleur with their first-round pick in the 1997 NFL Draft.

LaFleur only played four seasons with the Cowboys and the success was hard to come by. His best season was in 1999 when he caught 35 passes for 322 yards and seven touchdowns.

Overall during his career, LeFleur caught only 85 passes for 729 yards and 12 touchdowns.

4. Antonio Bryant (2002, Round 2, Pick 63)

Antonio Bryant fell all the way to the second round to the Dallas Cowboys because of character concerns. The character concerns were real, and it was what ultimately derailed his career. As a rookie in 2002, Bryant had a lot of success in catching 44 passes for 733 yards and six touchdowns.

In 2004, Bryant became upset with his reps and often times would go after Bill Parcells. The Cowboys coach gave him a second chance but the writing was on the wall for his time to be done with the team.

After the fifth game of the season, Bryant was traded to the Cleveland Browns in exchange for Quincy Morgan.

3. Morris Claiborne (2012, Round 1, Pick 6)

Morris Claiborne was all the hype coming out of college, and the Cowboys traded up to select him with the sixth overall in the 2012 draft. Claiborne started 15 games to start his career with the Cowboys, but he couldn't be trusted a whole lot during his rookie season.

The next four seasons he never played more than 11 games, and injuries are what really threw his career off track. After the 2016 season, the Cowboys moved on from him, and he signed with the New York Jets.

He would go on to play two seasons with the Jets and one season with the Kansas City Chiefs.

2. Ebenezer Ekuban (1999, Round 1, Pick 20)

The Cowboys haven't always had the most success with drafting on the defensive line, and Ebenezer Ekuban is a perfect example of one.

Ekuban spent five years with the Cowboys, and was a starter for the final two, but he never was able to put it all together and become a standout player.

Ekuban actually did find success later in his career with the Cleveland Browns and Denver Broncos, but that doesn't help the Cowboys and the first-round pick they spent on him.

1. Bobby Carpenter (2006, Round 1, Pick 18)

Bill Parcels coached Bobby Carpenter's father, and he influenced the Cowboys to select him with their first-round pick. Over his entire rookie contract, Carpenter only started three games, and that is nowhere close enough for a guy selected in the first round of a draft.

He finished with 3.5 sacks, but didn't have any interceptions or fumbles. In May of 2010, the Cowboys traded him away to the St. Louis Rams and received offensive tackle Alex Barron in return.

Carpenter also played for the Miami Dolphins, Detroit Lions, and New England Patriots before hanging up the cleats for good.
