Hey, Jack! I'm new here, too, so it seems a bit silly for me to welcome you. Regardless, I hope that you enjoy a long and worthy membership or whatever.
As for the Season Preview, I found it to seem rather plausible. As ryno4ever mentioned, I think there will be some improvements, especially in the rotation. I was sort of shocked, though, because I also wrote a 2007 Season preview and it was strikingly similar to yours.
Here's to a great season and good posting!
