Do you think that the DT rotation isn't going to be added to, because the Cards don't think they need anyone else, or that the Cards don't need anyone else, so the rotation is set. Those are very different questions.
On the first question, I say that the Cards need someone else at DT, desperately.
I like Suggs more than anyone in the draft for the Cards. If Newman is truly the best player in the draft, as some are saying, then we need to take him.
As for Leftwich, I have only this to say...
Pay attention, people! We have our QB of the future, and, like it or not, his name is Josh McCown. They said it when we drafted him as the 3rd QB off the board last year, and they said it the day that we signed Blake.
I give you my Kerouac 9's LOCK OF THE DRAFT: We will not draft a QB in the first four rounds. You can take that to the bank. Maybe next year, if McCown looks like the next Gio Carmazzi, but not this year.
