NONE of The Blues had much. I don't know about most people. But, when I was playing midget and bantam, if I didn't sleep most of a night, I was worthless. Sleeping for a "cat nap" for 3-4 hours (which is the MOST I could get after the sun comes up), didn't help much, at all.
I think that a lot of people downplay lack of sleep as only an "excuse" for losing that doesn't hold water. But I disagree. You could see that The Blues had no jump for almost 2/3 of the game, and their timing was way off. They lost most of the races to the puck, couldn't get good wood on their passes, shots, attempts to clear, couldn't put their passes where they wanted them to go, couldn't get their bodies where they EXPECTED them to be at a given time, etc.
I'm sure many of you know what I'm describing, if you've ever played when very tired, or played when you are too old. Your muscle memory of thousands of skating sprints from your "prime experience" tells you you will get to "X" point on the ice after 3 more seconds, and the puck will be there. The puck gets there, all right, but you are short a stride, the pass doesn't click (your team loses possession, or you miss the tip-in, or you can't make your planned hit, etc. etc.).
The Blues just didn't have it tonight, and likely would have lost even if Allen didn't let that shot go "through" him. They had almost NOTHING left for most of The 3rd Period. They couldn't get it out of their own zone and couldn't keep possession for more than a couple seconds. They were "lucky" it didn't end 6 or 7 to 1.
I know it's very early. But with The Hawks so far ahead, it's going to be very tough to catch them. I'd sure like to have home ice advantage in a Western Conference showdown with them.
