. . . By the way, I've never seen the team run out onto the field with less energy. I turned to my wife and said, "This could be one of those games." Sadly, it was.
I noticed that, too. At the time, being the optimist that I am, I said to myself, "That's a good sign. They have a business-as-usual attitude. You don't have to get hyped for every game. They are going to go out there in workman like fashion and pile up TDs and coast to an Akron-like victory." In retrospect, however, your interpretation was on target and mine was somewhere in la-la-land.
I noticed the same thing, and had SBH's concern. The team entered the field both lackluster and piecemeal. A set of players came out, then a trickle, then a few more, etc. The band seemed out-of-sync because they did their usual fanfare, and the crowd anticipated this grand entrance. Instead, we got this leaky-faucet dribble.
Now maybe that had nothing to do with anything, but I'd like to hear what was going on inside the locker room moments before.
