First off the Saints front office must be banking ir linebackers Amoux and Dunbar on being big contributors. Second they must be counting on Pressley and Ayodele on breaking through. Maybe Leisle coming off ir.
Second they must be moving Jenkins to FS, which means they may be thinking Sharper is not coming back. This would explain the number one selection.
Third they don't think Jamaal Brown will sign a long term deal. So they are planning his replacement.
I actually had the Saints taking Graham in the third round in my mock draft so obviously I agree with the pick. Graham has first round skills and will be a great replacement for Shockey in a couple of years. I think Thomas is adequate, but he does not have the skills Graham has.
Finally, there are still linebackers on the board that could be starters this year, as well as several dt. I like Misi at lb and Woods at dt.
I'd like to think they know more about the shape of the team than I do. So, I am willing to see what unfolds, but I still would have taken Kindle at one or traded down. If you needed a cb so you can switch Jenkins there were several good one to take at 64,
