I'm not sure why you (CM/RedDead/Husker Psycho) seem to have such a hard time admitting that several games last year came down to the outcome of a single play.
You'd be perfectly in the right arguing that we never should have been in those situations in the first place, but denying that the games actually came down to one play makes you come across like you have an agenda and will continue to argue in favor of that agenda regardless of facts.
No game came down to one play last year... or any other year... for any football team... ever.
Every play of a football game is as important as every other play.
That's why as players we were "coached" by every coach we ever had to give 100% effort on every play. Because every play is as important as every other play.
It's one of the most basic things players learn... in "football 101"... usually in grade school.
Okay, let's take your argument and apply it to two different scenarios:
Play 1) An end of game Hail Mary
Play 2) Earlier the same game: 1:14 left in the first quarter, 2nd and 2 on your own 32 yard line.
If you "lose" play 2, do you lose the game? Not necessarily.
If you "win" play 2, do you win the game? Not necessarily.
This play has the potential to cause many different outcomes in the game, thus does not necessarily have a direct impact on the outcome of the game (thought still MIGHT, thus the "give 100% effort every play" rule).
If you lose play 1, do you lose the game?
Yes.
If you win play 1, do you win the game?
Yes.
This play has ONLY TWO possible outcomes, each of which affect the outcome of the game in diametrically opposed ways. Thus this play is necessarily more important in determining the outcome of the game than is play 2.
Could you have avoided that play in the first place if you played better: yes.
But that doesn't change the fact that the game still comes down to that one play. If you win that play, you win that game. If you lose that play, you lose that game.
