You are right - the perfect storm of bad shooting for the Zags. By the end of the game they were even missing shots right at the rim.
But I also believe that SMC played a great game.
If both teams are at their best - SMC might make a game of it for a bit, but the Zags win going away.
If SMC has a bad game and the Zags have a good game - you get the blow out that we saw earlier this year.
If SMC has a good game and the Zags have a bad game - then SMC is good enough that they've got a chance to win. And they took advantage of that.
