I think this can be put in the same category as a segment I saw on ESPN a month ago.

Some mathematician calculated the "odds" of going for it on fourth down and said that most teams should go for it way more often than they usually do. When they presented this evidence to some head coaches, their reactions were similar:

"Sounds like a good theory, but has this math guy ever had his name on the front page of the sports section because he decided to go for a fourth down early, missed it, gave up a field goal, and lost by two points?"
