I could see Naps not fitting in with the Halos. If I remember correctly Wilson was getting in a few games for defensive reasons, ahead of both Napoli and Mathis.
One of the Angels / Red Sox games that year, Mathis airmailed a throw to centerfield, and a Red Sox fan remarked, "you don't see that every day!" I had to speak up and tell him that he didn't see the Angels all the time then.
