NCAA Men - Elevated shooter

[mick]

from http://www.detnews.com/apps/pbcs.dll...77/1004/SPORTS
... Referee Jess Kersey , now working for the league, was at the practice facility to discuss officiating and some of the new points of emphasis,

As for the referee's meeting, Kersey made the Pistons aware that the refs will be watching contested shots more closely. They will make sure that defenders allow shooters to land after their shots. Too many times, defenders' feet were going underneath air-borne shooters, causing them to fall awkwardly and increasing the risk of injury.

Questions:

• What is the NCAA Men's Rule for this act ?
• Is this being discussed in college camps/clinics?
• What are the "accepted" applications?

While watching this happen with regularity in the past, I find it troublesome.

Thanks.
