Well, I don't think it's impossible; I mean, why the talk of how to play the starters during the Houston series if the wild card were in hand? There are still statistics to be analyzed. I just think this time of year everything is pored over as games become increasingly important.
Yeah, I think I'd disagree with that. I mean, momentum is what it is; it can of course be stopped (or, for that matter started). But it generally requires more effort to do so. Much of a lot of sports at the highest level can be mental. I believe there are several studies that have shown higher confidence levels correlating with increased athletic performance.
Again, it doesn't mean the ride doesn't come to an end (the Cardinals were riding a 17+ game winning streak toward the end of last season), I just think even the players would enjoy entering a playoff atmosphere feeling they had some wind at their backs.
