I am not a huge Delmas fan because of the injuries and he needs to be able to practice. However, in Coyles offense I think Wilson could do a similar job to what Clemons did. I think Coyle would use Delmas different than he did Clemons. Clemons while solid has ZERO instincts, and Delmas has instinct and can make plays (when on the field) so he would probably be allowed to do a little more free lancing than Clemons did. It would also lead to a big play now and then, but it should produce more turn overs as well. If Wilson, or Thomas is in there he can always go back to the more conservative way he used Clemons.
If they bring Delmas in I would expect them to draft a FS in the mid to late rounds as well.
