Except that it wasn't a catch, and thus, by the original poster's logic would be an indefensible action by a Head Coach he is questioning.
What you are describing above is calling a strategic timeout. OK, fair enough. Not a bad idea. Not really a great one to burn timeouts either. Timeouts came in handy at the end of the game. Not sure burning another one would have been all that smart. But it makes some sense as well.
Bottom line is this. The challenge in the Titans game was fine. He had very little time to challenge the play, and quite frankly the angles that were first made available seemed like the Titans player didn't get two feet down. He challenged on his gut feel and from replays in the stadium. So be it. He lost one. Early in the game. Not all that big of a deal.
And yesterday, he could have challenged the Davis play. He would have lost the challenge. The catch was not completed. It was close, but there's no way that would have been overruled. It certainly wouldn't have been a brutal attempt at a challenge. But he didn't. Big Deal. They had plenty of chances to win that game yesterday. I thought despite some mistakes, that every coach makes, in every NFL game every week, the Bills staff did pretty well yesterday all things considered. They dominated offensively. They dominated defensively. They just couldn't finish. Pains me to say that, because I'm no Leslie Frazier fan by any means. But really, they played pretty well considering the roster.
Losing close games is starting to be a concern for sure. A couple of challenges here and there so far this year is pretty stupid if you ask me. The potential challenge yesterday was by no means clear cut. Especially when the call on the field was made the other way.
What really irks me about yesterday, is that I thought the Dolphins were going to roll the Bills. How could a team that has Tyreek Hill, Waddle, and Geisicki not? Well, Tua still isn't all that great. Miami is mediocre. Period. If Josh was the Miami QB, they would have scored 50 on the Bills. I fell into the trap that the Dolphins were a better team than they are. They really aren't. And when I realized that this Dolphins team was just mediocre again, it kind of pissed me off that we lost a game to an inferior opponent even though we were ridiculously banged up.
The Bills will slowly get healthier, and steamroll through the back end of their schedule. It's going to be a bumpy road the next couple of weeks. Just hope it doesn't cost them homefield advantage in the playoffs. They will roll Miami in December.
