We all love Howie, but that's a ton of money for a part time player who is injury prone. I guess he can play 2B only on occasion. Hopefully he can stay healthy. Cross your fingers.
370 PAs is about a 2/3 regular. Yes, part time, but more of a super-utility than a backup depth piece who spots a starter once or twice a week. he's a 4 -5 day a week player.
Not that fWAR is the be all / end all, but he's put up 6 WAR over the past 3 years, including one where he was hurt early and his time in Philly. There is a lot of value in this signing even if he's only a 1.5 WAR kind of player (half the value he provided last year).
