It probably had something to do with the two interceptions he threw in the last five minutes of the game.
I mean Romo's not blameless, but that loss was from a coaching meltdown, not a Romo one.
I think it's the other way around. Bad decision making ruins games, but
two interceptions in that amount of time and under those circumstances is inexcusable from an NFL quarterback, especially one as prolific as Romo. It also doesn't help that this is far from the first time he's choked like this. You can blame the decision making all you want, and it
was horrendous, but I still think Romo is to blame for that loss.
