Because in addition to being incredibly lucky, like the last Ravens win, I don't think it brings us any closer to the ultimate goal of winning a title, and in fact, may have taken us farther away. They're not winning 3 playoff games and beating the best of the NFC, FFS they're 3.5 pt home dogs to a team that's won 9 in a row with the best D in the NFL.
But since they won that sad division, Rooney will likely reward Tomlin with yet another extension and Rodgers will likely re-sign for 1-2 years, which means we remain on the treadmill of mediocrity for 2-3 more years instead of making the hard decisions to get back to championship football.
This is the kind of win Jets, Raiders, and Browns fans strive for. Have we set the bar that low now?
