Does he catch passes? ?
If you're saying that another DT to pair with Phillips is a need, why not sign Phillips to an extention first?
I get that they've underperformed as a whole, but look at the position as a whole: They've invested a first round pick, a 3rd round injured player who will be back next year, signed a guy in free agency (who they will likely try and extend) and overpaid Star (all while trotting out a practice squad player in Peko)
I HIGHLY doubt that they would put any more resources into a single position group when we have much more glaring needs IMO.
I'd argue we need a pass rushing DE more than another DT. And above all else, more play makers on O.
