That does not negate any game play and a scoring error like that can by rule be changed.
The correction was technically correct. The fact that it ever happened is what is inexcusable. The players at the free throw line should have raised a stink and stepped in the lane before they ever gave the ball to Homan - as soon as the official indicated 1 and 1 rather than 2 shots. If that is how it went down they have to share the blame. If he indicated 2 shots and then let play continue after a miss there is literally no excuse for that officiating.
In either case by no stretch of the imagination was it good officiating as the announcers applauded them. It would be very curious to see in an alternate reality if Kansas missed the three if they would have gone back to free throws and allowed Kansas to rebound after the miss - essentially giving them another bite at the apple. In Phog Allen, I wouldn't be surprised if they did. Or worse yet if ISU had blocked the shot and taken it down for a fast break layup before the error was corrected. Would ISU's bucket really be allowed to stand? That is the rule but the officials likely wouldn't have made it out of PA alive.
Just to rub salt in the wound, ISU went on to lose this game in OT. How did it get to OT? Kansas hit a jumper to send it to OT; a jumper that was counted as a three pointer but by many accounts the shooter had his foot quite clearly on the line.
Have a peachy weekend!
