Good grief, let’s try to use some logic, shall we? A coach isn’t going to publicly comment on a concern like that, not just because of how it can mentally affect our players, but also so it doesn’t bolster an opponent. I lived at 5,000 feet, and only the dimmest of bulbs would believe it isn’t a factor, and we know SF isn’t an idiot. Knowing it, and saying it, are not always going to go hand in hand.Frost did not seem concerned with altitude. And now we hear it is/was a concern.
