He was a 10th round pick in the Cowboys 1977 draft.
He had a 21 year career.
He was one of only 34 QB's in NFL history to have over 5000 pass attempts. He threw for over 34,000 yards and 196 TD's.
Only 19 other QB's in NFL history participated in more regular season games.
He played for six different teams......but not a single down for the Dallas Cowboys
He got cut after training camp. The Cowboys already had Roger Staubach and Danny White. However, the greatest factor was he was the 2nd QB the Cowboys took in that draft. They had drafted one earlier in the 2nd round.
He was Steve Deberg and, in retrospect, the Cowboys should kept him instead of Glen Carano, who they took in the 2nd round.
After being cut by the Cowboys, he was immediately picked up by the 49ers and placed on their practice squad. In 1978, he was the starting QB for the 49ers and the first QB to implement Bill Walsh's west coast offense. When Joe Montana was drafted the following year, he became the backup.
In Deberg was traded in 1981 to the Broncos under Dan Reeves as John Elway's backup.
Deberg was traded again in 1984 to Tamp Bay and was there when they drafted Vinnie Testaverde and Steve Young.
In 1988 Deberg was traded to Kansas City.
Do you recall the Thanksgiving game in 1993 in the snow in Texas Stadium? That's the game that Leon Lett touched a live football and the Dolphins were able to kick the winning field goal. You may not remember that Dan Marino was out with an injury. The starting QB for the Dolphins that game was Steve Deberg.
Peyton Manning called him one of the greatest play action pass quarterbacks of all times and claims to have studied film on his technique.
Deberg retired after the 1998 season at the age of 45 as a backup QB for the Atlanta Falcons, coached by Dan Reeves, the same year they went to Super Bowl 33.
