I advocated taking Vea even when we had Suh. If he's the best player available at 11, you take him regardless of the roster. We also knew Suh wasn't going to be with is much longer, and I think its pretty reasonable to say Phillips won't be either. You don't have to wait for the cupboard to be empty before you draft a position. I also believe DT is a core position on defense - right after CB and DE.
That would require several players to be off the board, and even then I'd consider Payne over him. Both would be a reach at 11, imo. Either way, we downgrade at the position and are left with continued deficiencies in the LB corps and FS (not to mention offensive deficiencies that I don't think we were going to address in the first outside of potentially a QB).
