I could say that the list of coaches who've had no losing seasons in 5 years is short, as well. He was 5-3 in 2010, for the record.
Put it this way...hypothetically, if we had Tony Romo in the games all this time, and played the same games with the same play calls....the only difference being that it's Romo making the adjustments at the line and making the throws. And, for argument's sake, let's say we make that extra play or two in each of these games and win the 5 of them that were in serious contention, putting us at 7-2 and not 2-7....would that mean that Jason Garrett is then a good coach and not a bad one, after all?
I'd submit that it wouldn't. That the won/loss equation in the NFL is complicated, and you have to look specifically at all aspects of the wins and the losses to see who's doing a good job, who is not, and who's got significant room for improvement. If I were seeing bad coaching or bad play calling contributing to losing games, I'd put it on Garrett and the coordinators. But that's not what I'm seeing. So I put the issue on personnel, instead, because that's where I'm seeing the biggest limitations right now.
