Obviously, you can't just turn PI into a 15-yard foul like a personal foul, because then it would give defenders an incentive to just mug receivers on every deep ball. That said, something needs to be done. What I suggest is that this be the minimum change: PI calls must add two things above and beyond what is currently announced: (1) the number of the referee who claims PI occurred, and (2) a clear description of the action taken by the penalized player who caused the foul. In other words, the referee must say "official number 110 states the defender tripped the receiver" or "official number 130 states the defender used an arm bar to impede the receiver's progress." I'd really love to see Mike Pereira defend these howlingly bad calls if they had to be that specific.
