We've seen and talked about what the media thinks the Rooney's will do, and what their options are, however what would you rather do IF Bill Cowher resigns as our HC after the game on sunday?
I think there are pros and cons to both to be honest. The benefit of promoting from within is that the coach already knows our system, is in good with the Rooney's, understand how and why they go about doing what they do. The players already know them, and the transition is generally easier all around.
Bringing someone in from the outside can be good though too because they bring fresh new ideas, a new staff, and can really jump start an organization; similar to what Sean Payton did with the Saints. However the transition can alos be a really long one, and take time to develop, meanwhile the team struggles to learn a new system, terminology, and generally get used to playing under a new regime.
Personally I'd rather promote from within, but then again BC was brought in from the outside to replace Noll and the rest is history !
