I think Steele's book has slipped this year. The writeups contains tons of filler and make it at times a difficult read.
Gold Sheet is pretty good and Fish I have always been partial to Gameplan. I have every football annual they have ever published. Joe Del Popolo does all the college writeups and has done a superb job with his analysis over the past 35 or so years.
