Russell Maryland was the first overall pick in the 1991 NFL draft. Maryland was on the Cowboys until 1995 and he was one of their best defensive lineman. In 1993, he was selected to the Pro Bowl for his outstanding play.
Maryland was very stout against the run and gave great effort. Maryland was a good contributor during the Cowboys' three Super Bowl wins.
While Maryland had a lot of team success, he did not have as much individual success as some others on the list did.
Greg Ellis was the eighth overall pick in the 1998 NFL draft. Ellis was a very productive defensive end for the Cowboys until he left in 2009.
Ellis was not only an impressive pass-rusher but he was also very reliable against the run. In 2007, Ellis won the NFL Comeback Player of the Year award because he was very productive after returning from a torn Achilles tendon.
Unfortunately, the Cowboys were not very successful while Ellis was there. The Cowboys did not win a single playoff game while Ellis was there. Because of this, Ellis did not make the top five.
Alvin Harper was the 12th overall pick in the 1991 draft. Harper was drafted to mainly give the Cowboys another receiving threat to go with Michael Irvin. Harper was a very productive No. 2 receiver until he left in 1995.
Harper is best known for his 70-yard catch and run to get the Cowboys in field-goal range to win the NFC Championship game in 1992. Harper was a part of the Cowboys' Super Bowl-winning teams in 1992 and 1993.
While Harper was a productive No. 2, he was not as productive as some other players on the list. Harper was never the primary target for the Cowboys so his production suffered.
