The toughening box and injuries explain most of why the officiating is having such a devastating early effect on our bigs and why other team's bigs not injured are scoring and rebounding despite getting fouled up, too.
But I want to add one more trigger.
The lingering influence of Jeff Withey has finally receded and players AND coaches seem to have forgotten what the great savant of block and alter taught.
1.) Don't leave your feet when they drive at you. Extend arms fully and arch your shoulders back. Don't reach toward the shooter.
2.) When you leave your feet, jump straight up and reach straight up. Don't move into the shooter or reach toward the shooter.
3.) Block the shot a foot away and above the shooter.
4.) as you come across the lane, wait to commit to block a shot until the driver leaves his feet, so you know he can no longer change directions and jump into you.
Such varied players as TRob, Tarrick Black, Hunter Michelson and Jamari Traylor each learned these lessons from Jeff, or the knowledge left behind, despite having to jump more explosively to make up for their shorter heights.
Jeff understood that altering was more important than blocking, because you can alter more shots than you can block. He understood you can alter shots simply with footwork, position, and extension at the right moment. And altering, like blocking, occurs about 1-2 feet from and 6-12 inches above a shooter's release; not at the point of release.
This season KU's bigs are trying to block shots the way kids in my neighborhood used to do it. They are blocking at point of release. Duh! They would have been fouling under the old rules, too.
Time to get out the old footage of Jeff.
Jeff got so good they let him block some at point of release, because he arched his back and created the illusion of leaning back from the charging driver. But before he did that, he had learned to block and alter without being in the shooter's immediate space. And well above the point of release.
