I do not see any way that Marrone returns to Syracuse next season and do not believe that he is posturing/leveraging. If he does not get an NFL head coaching position (I am convinced he will get one), I do believe that Marrone will selectively interview for collegiate HC positions and I do not believe it will take a ND / Oregon / SEC job for him to make the jump. Remember that there were rumors floating around several years ago (unverified) that Marrone was close to leaving SU for a comparable collegiate HC position after the first Pinstripe Bowl victory. It is a shame because this is a staff that is so strong from a scheme, player development and game planning perspective.
This comes at an awful time for Syracuse. While Marrone has rescued this program from disaster, he has done so through superb game planning, attention to detail, precise execution and player development (similar to UCONN's BCS run under Edsall) as opposed to high level recruiting and stockpiling of talent. While the program is absolutely turning the corner - it is also at a very fragile state - and at risk of slipping back to mediocrity.
With the move to the ACC - it is time for Syracuse to decide whether it wants to allocate resources to make a run towards being a program that competes regularly for BCS appearances. I really think that the next two weeks are going to shape the future of the program for the next 10 years. Very interesting times ahead.
