They really didn't. They held the Titans to 17 in regulation. Then in OT they did let a lot of clock go, but they ultimately held them to a field goal which was one of the scenarios we needed. We lost the game because we had an unneccessary risky pass thrown before the two minute warning on a 1st down play when we were about 20ish yards from field goal range.
We lost because of our offense having the inability to score. We put up 3 points in the entire first half. We only scored 17 points on the last play of regulation to give us a chance to keep playing. Our defense got us the ball back in OT. The offense lost the ball.
If your defense holds your opponent to 17 in regulation in the modern NFL and that is too much for your offense to win the game, that's an offensive issue. If your offense has plenty of time in OT to tie or win the game and they give up the ball, that's on the offense. They could have had half the field at the 2 minute warning in OT. Very maneagable situation.
Our defense was out there for nearly 40 minutes. Of course they were gassing by the end.
