If you have not done it by post season don't expect to do it then.
It happens all the time, and that's why many call the playoffs a "crap shoot."
One could have easily argued your point in 2004 after game 3 of the series with the Yanks.
It can be done. It often is.
This team has, on numerous occasions, had incredible hot streaks and incredible great pitching stretches. They've done this more than any other team in MLB, perhaps in years and years.
It doesn't seem logical to me to think some team who has shown less ability to turn it on and be great should be expected to be "on" for the playoffs more than we should expect the Sox to be.
Yes, our pen has looked crappy for a long while.
Yes, our bats have gone cold, and our power declined, of late.
We had other down times this year, and I heard the same "sky is falling" mantras several times, and then there were crickets again and again, as sure enough, we went on a tear again.
Can I guarantee we will go on a tear starting October 5th or 7th? Of course not, but looking at our team, I like our chances of being the best team, when it counts, more than anyone else.
Honestly, that's how I feel.
You don't win 103 by September 20th by luck.
