Free agents of note

Mike NapoliMike Napoli, 1B: Napoli was not on my top 50 free agents, and I received more questions about him (including one from my editor) than any other player who didn't make the list. (Note that I didn't receive any questions about any other player who didn't make the list, so that wasn't hard.) Napoli got plenty of playing time -- only five free agents had more plate appearances in 2016 -- and didn't do much with it, striking out in 30 percent of his at bats, posting a .335 OBP and providing no defensive value whatsoever, so he's really just a DH with some power, but not Mark Trumbo-level power. This represented about one win of total value, and that was an improvement over what he provided in 2015. He'll play at 35 in 2017 and is probably a platoon DH who should sit against at least good right-handed pitching, which is not a player I'd give more than $2 million given the shortage of bench spots for hitters.
