5 Biggest Week 1 Blowout Wins in Cowboys History

2. 1978: Cowboys 38, Colts 0 (+38)

Throwing it back a little further now, the Cowboys ended up losing the Super Bowl in 1978, but this was another season where it was clear from Week 1 that Dallas wasn’t playing around.

Coming off a Super Bowl win, Tom Landry’s team was ready to prove that they weren’t going to rest on their laurels, and the Colts were the whipping boy that let them prove that.

This was another game that started a little slow, with a 0-0 score after one quarter, and then the Cowboys completely ended the game in the second.

Doug Dennis pounded in a 1-yard touchdown to open the scoring, then Roger Staubach hit Tony Dorsett for a 91-yard score and Billy Joe DuPree for an 8-yard score. There was absolutely nobody who thought the Colts had any shot at coming back from that 21-0 halftime deficit, but the Cowboys really cranked up the heat just to be sure.

Staubach threw another two scores in the third quarter (38-yarder to Drew Pearson and 1-yarder to Jay Saldi) before Landry decided to show some mercy and get a few backups into the game.

You almost feel bad for Baltimore QB Mike Kirkland, who had sacks and interceptions (5 and 2) on almost as many of his 27 dropbacks as he had completions (9).
