You said "Anyone who thinks there's only a few plays separating 10 wins from 5 wins is smoking some amazingly good stuff."
It's not crazy for 5 plays to be the exact and direct reason for losing in 5 games. 5 plays qualifies as a few by most people's definitions of the word. I'm not making a bigger point or rationalizing anything. Just letting you know that your statement, as quoted, isn't true.
It was absolutely true.
No single play is the "exact and direct" reason for an outcome.
There's a world of difference between a 5 win season and a 10 win season. And to claim that it's only a matter of "a few plays" is completely misguided.
It's rare that the outcome of a football game is affected by the outcome of one specific play -- the '84 Orange Bowl, the '94 Orange Bowl, '97 Missouri, '13 Northwestern -- famous examples of where the outcomes of the game could have been completely different had one play gone differently. This is in comparison to something like the 2001 Colorado game (or the 2014 Wisconsin game, 2012 B1G Championship Game, 2011 Wisconsin, 2011 Michigan, etc) where there was no single play that, were its outcome changed, would have changed the outcome of the entire game.
Now the outcome of these One Play Decides games could have ALSO gone differently had one team played significantly better or worse for the entire game, but that's the case in ANY game. It's NOT the case in any game that the outcome of one play dictates the outcome of the game.
The One Play types of games are fairly rare. Anecdotally, I'd say probably one or two a season at most.
In 2015:
BYU - sack the QB or knock down the Hail Mary and we win the game
Wisconsin - block the field goal and we win the game
Illinois - convert that dumb third down and we win the game
Now play better the whole game (which is what I think you're saying) and it won't matter anyway, but if those three plays go the opposite way, those 3 loses become 3 wins.
In addition to that, there were the 2015 games where one play wouldn't necessarily have guaranteed us a victory, but likely could have led to victory -
Miami - don't throw that interception in overtime and there's a good chance we win
Northwestern - convert the 2pt conversion and we have a good fighting chance at winning
On the flip side of this, the MSU game was an instance where one play determined the game in our benefit. So there were 4 games in 2015 where, had one play gone differently, the outcome of the game would have changed -- 1 in our favor, 3 against us.
Now this point exists not as a way to make excuses for anyone, but simply to point out that the team wasn't as bad as one would believe were they simply to look at our Win/Loss record. Yes our pass defense was atrocious. And yes there were issues at QB with game management and turnovers. But there's hope for 2016 because a lot of the loses in 2015 -- Illinois in particular -- were due in large to part to transition year bullsh#t/miscommunication that they should be able to get cleaned up in year 2.
If in 2016 we see several more One Play Decides games -- even if they come out in our favor -- then it's a sign of problems and any griping will be warranted.
