Michigan has been unlucky so far this year. Sometimes it is hard to believe in luck or statistics. We don't want to believe that things are haphazard.
Nobody is arguing that UM's defense is great or that the closeouts are awesome or that people aren't getting lost on screens. But with six minutes left in the game, Michigan down by four, 30% 3pt shooter freshman Anthony Cowan takes a step-back off-the-dribble 3 pt with Walton doing some form of contest. If you'd shown that shot at the beginning of the possession to Turgeon and Beilein and asked if they'd take it or would play a new possession, it would be an easy decision for both of them. If you'd shown NIckens shots (but not the results) to Turgeon and Beilein before the game and offered 50% (2 of 4) to both, it would have been an easy decision for both.
This doesn't mean Michigan is losing because and only because of bad luck. It means that they've played well enough to be in position to win their B1G games but bad enough that some bad luck could swing some of the results. If they played those games 100 times at exactly the same level, sometimes they'd be 3-0, sometimes 0-3, sometimes somewhere in between, based purely on luck. My guess is that the most common result would be 2-1, but who knows.
Luck tends to even out over time and even over a season, although of course not always. I'm still hoping Michigan's luck improves over the next sixteen games. But I'm also hoping they play better.
