Caldwell did interview twice but apparently the second one was with Caserio (he had met with Easterby previously). Both Culley and Frazier have met with Caserio twice. So take that for whatever that's worth.
I wouldn't mind losing Culley in all honesty. Picks help but I'd also just be open to getting a different mind in those offensive decision making meetings.
We really don't know how involved Culley was in The Ravens passing game but The Ravens do have internal options to replace Culley as their wide receiver coach. I think current assistant special team coach T.J Weist could be the guy and James Urban may be promoted to passing game coordinator.
