When the coaching vacancy puzzle has been pieced together (more or less).
Lovie Smith is still out of work.
Ray Horton is rumoured to be let go by the new Cards regime for Todd Bowles.
So what do you say? Any reason for the Pats to pursue those guys? I realize it may be stepping on the toes of Matt Patricia and possibly Pepper Johnson but in my mind the better defensive coaches this team can assemble the better the chances of sustained success even after (God forbid) Tom Brady chooses to ride of in the sunset. Add to that the further chance of winning SB-titles when Brady is still around.
It may be impossible to get those guys without offering the DC position.
