CC Sabathia, supposedly the New York Yankees' ace pitcher, is 33 years old and 290 pounds. More to the point, he is out for the rest of the season (pessimistic reports say for the rest of his career), with injuries. This, despite the fact that he is owed $23 million each in 2014 and 2015, $25 million in 2016, and up to $25 million in 2017.
My guess is that the Yankees have protected themselves by buying insurance. How much might that cost, and how much more might it cost for Sabathia than for someone else who is now 28 years old, and weighing 240 Pounds with a similar salary? Put another way, how much does Sabathia's "extra" age and weight cost in insurance, quite apart from the fact that these factors make it more likely that he will break down?
