This reminds me of a story 20 years ago when Pittsburgh Steelers (American football) announcer Myron Cope ran into head coach Bill Cowher...

Myron said, "I see that Lee Flowers is playing today after a high ankle sprain 2 weeks ago. But I thought that high ankle sprains took 4 weeks to heal. What gives?"

Coach Cowher replied, "4 weeks is true, Myron, for the first high ankle sprain. But if you recall, Lee had a high ankle sprain on the same foot last year. And since subsequent high ankle sprains only take 2 weeks to heal, he's ready to play."

Myron paused and asked, "Then why don't you just take the whole team out in February and sprain all their ankles?"

(We laughed 20 years ago. Nobody's laughing today.)
