Did he start a Superbowl for the Cowboys? I think we all know the answer to that. He probably barely ever even started a game. Hollow victory.
Salary Cap came into play, look how those Niners and Cowboys dynasties did then!
The Dallas Cowboys signed Kosar to a one-year, $1 million contract in 1993 to fill in for an injured Troy Aikman. Kosar performed well in four games for the Cowboys and earned his only championship ring as a backup in Super Bowl XXVIII. Kosar entered the game in the final play and knelt down to close the victory. A week prior to the Super Bowl, Kosar relieved an injured Aikman in the second half of the NFC championship game against the San Francisco 49ers, completing five of nine pass attempts for 83 yards, one touchdown and no interceptions.
