If true I think it's a mixed bag for us and/or them. Dungy did more to make that collection of offensive talent and guys on D a team than I think any other HC could have. He gradually shifted the focus from overwhelming offense to team performance while building a pretty good inexpensive cover 2 D. Of course that D may be expensive to maintain going forward and that could impact the offense. Or Polian could go hog wild to recharge his O. And absent the conservative approach of quiet strength...Manning may revert to form, as he did a little against SD. Dungy was a buffer between lots of factions on that team that could get under each others skins. His downfall was really the ultra conservative rest/rust thing. Sometimes intensity and a little channeled agression is what your team needs. Not brain numbing cumbayah.
Team could implode, come together to support succession, or just continue to do what they do.
