You know it's true.
With the real NFL season here, but with only having one week of games, there will be plenty of overreactions. Heck, Cardinals fans know about how things can change. We saw a 4-0 start to a season end 5-11 in 2012. Heck, I even remember the vibe in the locker room -- that season felt special to start out, with how they were winning games.
In the Bruce Arians era, Arizona lost their season opener in 2013, falling to the St. Louis Rams, giving up 14 fourth quarter points.
