Query: Very disappointing revision:

I bought the 2006 edition of this book automatically, as I have for a number of years. I am extremely disappointed with the totally revised content, as I find it much more difficult to use. While it would seem logical to group the records together as done in the new volume, it just doesn't work for me. The old layout of team info, with each team starting at the top of a page, has been junked, and the results are not pretty. Furthermore, this is now just a record book; the old "facts" sections, including a review of the preceding season and a preview of the new season, have disappeared. I'm keeping my 2005 edition and trashing the 2006. I hope Sporting News comes to their senses and arranges the 2007 edition like the 2005 and prior editions.
