I can't argue with that and from my replies above, I think it should be clear that I do believe that variance is the single biggest factor at play here.
Nonetheless, I do think there is something to be said for the market having been slow to adjust to the way the game was being played in the early weeks of the regular season. All sorts of average passing yards records were/are being broken and consequently more points scored with higher average margins of victory. Combine the above with correlation between the 'tracking line movement success' and 'favourites covering the spread' and you have a hypothesis worth testing
