Dallas Cowboys Myles was selected by the
Dallas Cowboys in the third round (62nd overall) of the
1991 NFL draft. As a rookie, he was limited in the preseason with pain in his right shoulder, caused by a screw, from a surgery while at college, that was too long and tore at the muscle. He played in the first 4 games, before being placed on the
injured reserve list on September 25. In , he was
Ken Norton's backup at
strongside linebacker, playing mostly on passing downs, while registering 21 defensive tackles, 9
special teams tackles, 2 quarterback pressures, one pass defensed and one interception. He was the starter at
outside linebacker in
Super Bowl XXVII when he suffered a freak injury, tearing the anterior cruciate ligament in his right knee during a
touchdown celebration, after he was shoved from behind, slipped and twisted his right knee. In , the recovery process from his injury took him until week 9 against the
Philadelphia Eagles to return. He was a backup at
strongside linebacker behind
Dixon Edwards and tallied 17 tackles. It has been speculated that he was never the same player after the injury. In , he competed for the
middle linebacker position after Norton left in
free agency, but the job went to
Robert Jones. He was a backup to all three
linebacker positions, collecting 13 tackles and one quarterback pressure. During the
NFC championship game, he was forced into early action after Edwards was lost with a dislocated shoulder. In , with
Darrin Smith holding out for most of the season, he started the first 7 games at
weakside linebacker and 4 games at
middle linebacker in place of an injured Jones. He finished third on the team with 99 tackles, while playing through a separated shoulder and helping the team win
Super Bowl XXX. Myles returned to the Cowboys for his final season in , but his playing time was reduced and he never started again. In his six-season
NFL career with the Cowboys, he was overshadowed by other players and was mainly used as a backup linebacker and
special teams player. During that period the team won three
Super Bowls (
XXVII,
XXVIII,
XXX), and he finished with 135
tackles and two
interceptions.
