Sometimes, you just have to ask yourself, "What would Tony Vitello do?"
------------------
Since we can never know for sure when an injury might not be fake, why not fight the fakes by going overboard in the opposite direction?
When an opposing player goes down and the ref stops the clock, immediately send two carts with loud sirens onto the field. One cart carries a priest, a Pentecostal pastor, and a rabbi. When the cart gets to the downed player, the clergy jump off, kneel on the field around him and begin praying aloud.
The other cart brings out a freshman assistant trainer carrying AED shock paddles, and a burly, bearded trans nurse carrying a huge syringe with a long needle, and a one gallon enema kit.
The Pride of the Southland band begins playing a slow, New Orleans brass band version of "Just a Closer Walk With Thee," while the women in the stands begin that spooky, high pitched ululation sound ("zaghrouta") that we associate with middle eastern funerals.
When a player knows stopping the clock is going to cause that much ruckus... we can at least assure that he's committed to his injury.
