Just took a quick look at your game, and obviously the reason you lost was because you shot 27% from the field. Not gonna win many games that way. Why did you shoot 27%? Hard to say, but it may have been one of those games where the shots just didn't drop.
I don't like to use that excuse/answer because, being a numbers guy, I think that the engine should follow the ratings closer than it does, with less "randomness", so to speak. But the engine is what it is, and sometimes you just get a bad roll of the RNG dice. It sucks when this happens (and wait until it happens to you in an NT game where you're favored. You think you're upset now, ha!), but there's really not a whole lot you can do about it due to the limited options we have available to us as coaches.
The best advice I ever took off of these forums is this: No matter what you do, there will always be the possibility that your team will get beat, even when you're the far more talented team. The best thing we can do from a coaching standpoint is to try to limit those occasions through the few options we have available to us. In other words, do your best to decrease the odds of that upset happening. Can you guarantee a win 100% of the time? Obviously not, but you can get it really close to that and that comes through experience, trial and error, and solid game planning. I don't think you did anything blatantly wrong in your game, I think it just wasn't your night. And like I said earlier, it sucks when that happens........
