Anyway, I will be getting into more depth about my opinions on team needs in the next offseason preview post, however, I thought I would point out that NFL Draft Countdown (link on the right of page) posted this article. This is the first good breakdown of team needs for the entire NFL that I have read.
Things to point out. Only 5 teams are listed with RB as one of their top three needs: AZ, ATL, DAL, OAK, and SEA
Also, 4 teams have tight end listed among their top three needs, Buffalo, Detroit, Seattle and Ten.
Now of course this is all subject to change throughout the free agency period.
