Unfortunately, senior administrators will simply make and enforce rules that make their lives easier, even if it is corrosive or malignant to the game. A coach can't govern his behavior after his team got blown out on national TV? Well, eliminate the handshake line. Problem solved. Second-order and unseen costs to the game? Meh, who cares? My job won't get more difficult and won't require leadership.
If you haven't seen it, I recommend watching Izzo's presser on the topic yesterday, particularly the first half and the portion concerning the handshake line beginning at 2:45. It's instructive, IMO. And there's a nice shout-out to TF and Trayce J-D. The Detroit Free Press article that contains the embedded video isn't paywalled:
Tom Izzo: “When I watched it on a big screen and I saw people swinging, I saw the fans right behind them, it reminded me of the Malice in the Palace."
