As for "playing to not lose," I think that can be viewed as a misconception of the West Coast offense. Its not like he's changing his philosophy mid-game so that they won't lose. Its the same mentality in the first half as it is in the second half.
Sure, maybe they slow it down a little bit. But at the same time, the defense turned up the heat in the second half.
The Bison scored 336 points in the first half (22.4 ppg), and 245 points in the second half (16.3 ppg). The defense allowed 105 first half points (7.0 ppg) and 64 second-half points (4.3 ppg). Yes, that is the entire season.
If they were playing to not lose, the defense is where you would see them take their foot off the pedal, not the offense.
