High-school hotshot pitcher Rick Porcello has apparently been signed to a 4 year major league contract with the Tigers for 7.3 million. Does this make sense? Hmm, let's see. $1.825 million per year. 2 year development time. 50% chance of flameout/arm problem (the Roger Salkeld/Brien Taylor Experience). 25% chance of inconsistency/arm problems (the Kerry Wood Syndrome), 25% chance of greatness (the Dwight Gooden Goldmine). $8-$12 million per year for mediocre starting pitching on the free agent market as your alternative.
Economists, start your calculators.
