The rule is killing football both college and pro. It’s completely subjective and carries the biggest penalty with ejection from current game and having to sit out half the next one.
There is no clear definition of the rule which involves multiple factors.
No official or replay official wants to be the one who misses a call when a player does really get hurt so they flag or question every hit which is almost always results in an ejection.
Then your conference commish looks like a fool defending his officials who did miss a blatant targeting hit.
