Napoli had a great PHIL rating yesterday, but Murphy's was actually better:
He went 2-for-4 with a big defensive play, so that's probably why his Performance level is high. As a call-up in his first MLB game, he showed alot of heart by coming through for the team, which is why his Heart rating is way up there.
Compare that to, say, a recent day from the Great Barry Bonds:
He mashes, and he has an average integrity for the game (he's Willie Mays' godson, fercryinoutloud, despite the steroid allegations).
I'm not sure how PHIL compares to VORP, but it seems clear who the more valuable player is.
