It’s hard to believe, but with a win on Sunday the Dallas Cowboys would have their first win streak for season-openers under Mike McCarthy. For a coach that had to speak up himself about the apparent numbness towards rattling off 12 regular season wins three years in a row, last year’s 40-0 beatdown at the Giants was the first time McCarthy’s team started 1-0 in the process of doing so. Opening against an NFC East opponent they’ve dominated for a while now may have been the key in reversing this Week 1 fortune, and though they won’t have the same advantage on Sunday, there are some ties back to recent NFC East matchups that should be telling about how Dallas starts the season.
