For whatever reason, some teams just can't seem to find any consistency from week to week, and the roller coaster ride isn't fun. Some teams, like the Lions, just don't have any discipline and make silly mistakes on a regular basis.
Other teams, like the Philadelphia Eagles, are led by quarterbacks who do their best to imitate Dr. Jekyll and Mr. Hyde and submarine their team's chances.
These are the teams that can't be counted on for anything, except, you know, they're going to cause you to lose your mind.
Michael Vick is like an artist that produces horrifyingly bad paintings much of the time, but sometimes, we see the inner Rembrandt come through.
The Philadelphia Eagles are 3-1 to start the 2012 season, and they've won their three games by a total of four points. Two of the three were won despite Vick's best efforts to sabotage the game, too, as he combined for seven turnovers in the team's first two victories.
I will say this, though: If Vick can start playing like he did against the New York Giants on Sunday Night Football in Week 4 on a regular basis, the Eagles have a good chance to make a deep run in the playoffs.
Whether you like him or not, it's clear that Tampa Bay Buccaneers head coach Greg Schiano has instilled a will to fight in his young team that wasn't there last year.
Through four games, this team has a points differential of minus-nine, meaning they are in every contest until the bitter end. Their 1-3 record could well be flipped around, but so far they haven't figured out how to get the job finished in the fourth quarter.
The biggest thing I worry about is that Schiano's tough-guy approach will wear thin after a while, and instead of rallying his troops, they'll start to turn on him.
You can't count on the Dallas Cowboys to play good football every week.
To be honest, this team has only really had one good week—Week 1's primetime win over the New York Giants at MetLife Stadium.
It's fun for Cowboys haters, but I can't imagine what the folks down in Texas think about their team.
Jerry Jones hasn't had a really good team since Jimmy Johnson was coaching, and though we've heard reports to the contrary (h/t ESPNDallas.com), you have to believe that Jason Garrett isn't going to last much longer.
No other team in the NFL shoots itself in the foot more often than the Detroit Lions.
From the top, down, the entire franchise isn't quite right in the head, and it starts with head coach Jim Schwartz.
Discipline and self-control don't rule this bunch.
Instead, what we see every Sunday is a hodgepodge of highly talented and skilled players and coaches who don't know the first thing about operating like a true team.
From multiple off-field issues (h/t ESPN.com) to unconscionable mistakes on the football field, like going for it on fourth down (though they didn't mean to; h/t USA Today's Chris Chase), this team is the worst of the worst when it comes to unprofessionalism and not playing up to its potential.
Schwartz's time in Detroit is coming to an end, if I'm not mistaken, and the Lions will be better off for it.
