I haven't followed Connor much, but looking at his stats, I'm not sure that he is actually an upgrade over Foote:

In any event, I'd rather see the Steelers keep Timmons inside. He was awful as an OLB. If I recall, he got no pressure despite being asked to rush quite a bit due to his unfamiliarity with the other responsibilities.
