Slice and dice it however you want — I prefer comparing every player in their age 22-through-25 seasons to Harper, who ranks 57th on that list — and you'll reach similar conclusions. On a 10-year deal, you're more likely to get a future Hall of Famer, maybe even a Frank Robinson, than you are to get the age 26-through-35 stats of one of Frank's best friends, Vada Pinson, an identical Harper comparable (in WAR) at age 25 who wouldn't have been worth the mega-money.
