Think of it as the meme stock period. When the professional investors couldn’t keep the line accurate for the price of GameStop? Same concept with BYU non-bettors although not as extreme!!
Eventually, betting lines will normalize as notoriety gets out (think several games or half a season), professional bettors get involved etc., but to argue there’s never any discrepancy or inaccurate lines is inaccurate, just as GameStop normalized from the craziness w/ time, but it did take time!
