If I had to identify a few of the coaching decisions I thought were questionable, I guess chronologically:
(1) Choosing to receive the ball to start the game (the most benign of these 4, but getting the ball second only helps a defense known for ramping it up to a new level in the 2nd half)
(2) Not calling timeout at the end of the half (Michigan missed this FG, but if Chryst had called TO around 30s, the Harbaugh may not have elected to kick from there (missing, as Michigan did, would have guaranteed UW the ball and time to get into FG range).
(3) Though I think it made sense for UW to lean into the pass game, there were many 4th and short downs on Michigan's half of the field where they punted. You have that OL and JTaylor. Use them, right?
(4) Chryst punted in the 4th when the score was 24-7, which was a kind of forfeit. But then after Lavert's pick-six, he decided to go for a score and even kicked onsides after that TD drive. The second parts are good and competitive. So why was UW punting at 24-7 in the 4th?
