They don’t, in fact, call him fat (having "a gut" is as far as they go), but everyone’s favorite nerdballers at Baseball Prospectus (who we usually love) come darn close, as they weigh in on the David Ortiz extension. It ain’t pretty. Among the indignities? Ortiz being compared to Ken Phelps, Willie Aiken, and Bob Hamelin, and BP’s self-appointed uber-economist Joe Sheehan insinuating that Papi may be the second coming of Mo Vaughn. I find this pretty disputable from a purely observational standpoint having seen both of them play many times. Sheehan seems highly uninterested in such nonsense, such is the M.O. for the gearheads at Prospectus, where watching a game sometimes seems like a secondary or tertiary endeavor — the numbers being the primary method for understanding the truth. Sheehan ends the article with some nonsense about how the deal isn’t financially sound, but since Sheehan has as much access to the Red Sox’ books as we do, we’ll just let this one go without comment.
