Power plays have been tough tonight (as has been rumored so far this year).
From this game alone, I sure can't point to an obvious flaw. You kind of have to tune out the announcers -- when the Sioux are cycling and lose it they say "you can't just keep looking for the perfect shot, you have to fling it at the net and hope for a good bounce", but if the Sioux took a bad shot they would certainly say they have to take the time to set it up. My first theory based on watching would be that the Badgers have a pretty good kill, as they often seem to step right into our passes, but that wouldn't explain previous games' futility. It's a small enough sample that it could just be bad luck, but it sure is disappointing.
