I’d have to go with Caserio because his fingerprints on are on the entire team and the drafts and free agent additions in recent years have been outstanding. McDaniels has to be one of the hottest head coaching candidates and he’ll be able to choose any opportunity he likes (hopefully in the NFC). But Caserio is a vital piece to complement Belichick and one who I think has really done a better job than Pioli did before him.
