I think that's a solid choice for that points system. I wonder how much Cust will play, overall, but he is a great matchup play.
I think catcher is a judgement call. There are decent arguments for any one of those three. Personally, I'd probably go with Posada or Napoli -- even though Suzuki played constantly last year, he barely did anything in runs and rbi, and my guess is that the extra homers you get out of those two will make up for the extra hits that Suzuki will get. I think they have more upside, and there will probably be decent ww catchers in a 10-teamer, so I don't think it's a huge risk. So that's how I'd go, but I've heard some people argue that Suzuki should show more power this year. If you believe that (I'm skeptical), he's a good play, too.
