I was curious why shortening games was deemed necessary. Honest answer. Haven't seen the data reflecting that viewership as a whole is overwhelming in favor of shortening games. My home is in Texas and the only game I would be interested in attending would be the Hawkeyes but the distance is too great. So, I DVR all televised games. Then fast forward through commercials, on-field play reviews, and halftime,. Not because the game is too long but rather to maintain continuity of play. BTW, wonder if anyone has asked the players? My sense is they might well keep,or tweak, the game procedures and do away with commercial breaks, and extended referee reviews. This to maintain intensity. If the game must be shortened further, then reduce the half to 15 minutes. If that is still not enough then reduce the length of quarters. But then what do I know? I am not 90 so 3 hours is not 7 minutes. I am, however 80, time still crawls, and let's say I have a different perspective.
