You may be right. I just see them like the '08 Dolphins. They're barely beating bad teams. They'll make the playoffs, but they won't last.
That's fair, but the way they play means they simply aren't going to be blowing teams away, and that they are probably going to lose a game or two to teams that they shouldn't. But playing defense, being able to run the football, and winning the turnover battle can help you win in the playoffs, so this team is built for that.
And not for nothing, but they have only had 3 games that they've won by less than a touchdown...Dallas, Houston, and Cleveland. They've won all of their other games by at least 9, with an average margin of victory of just over 15, if my math is right.
