I would have been doing the same thing...playing a big minus (I'd have gone -3, but nothing wrong with the -4 you had -- same principle) and begging them to shoot over the top of it all game. I was going to say there's no way that team approaches 7-for-16 in another game this season, but then I noticed they'd gone 5-for-10 just two nights earlier, which also makes no sense with those atrocious perimeter ratings, especially since it's a non superclass Sim team, so you can't even explain it away with huge IQ differentials or something.
Mark it up as a head-scratcher, realize there's probably nothing you could have done against that particular set of random numbers and fight on. You've got a good team there.
