My thoughts that I shared in the supporters section earlier this week:
The interesting thing moving forward and looking to 2013 and on is the current staff on the team. A new HC will probably be looking to bring in some of "his guys" and will not just take over a job with every assistant position filled.
Looking at the current staff I think after this season we'll see a few things happen:
1. retirements of Arbuckle, Burtnett, and Beers. All friends of Pflu who are probably not looking to further their careers as coaches for much longer anyways. These guys might not have the energy or drive to handle another regime change and might just consider retirement rather than interviewing for their jobs again. Oviatt might also fall into this category, I'm not sure if coach O is thinking of retirement soon.
2. Alternate job offers for Williams, Baker, Legi, and Gragg - all younger and considered up and coming position coaches who, depending on the 2012 season, could be hot prospects for an FBS team to scoop up or an FCS team to promote to a higher-up position.
3. Relatively unknown prospects for Gregorak, Rosenbach, Oviatt, and Green. Why? Well Oviatt could be winding down his career, although an entrenched S&C coach is a good thing to have if your planned regimine matches up. Gregorak and Rosy are in their first years as coordinators and Green is in his first year as a position coach. All three could get jobs elsewhere for sure, but a new coach (if the planned systems stay the same) might be thinking of someone else to be his top coaches at the DC/OC position.
It's impossible to guess now but I'd venture we see at least 3 retirements and probably 3 or 4 transfers out after the 2012 season. The degree of uncertainty with a new coach coming in might lead the younger coaches without a lot of ties to Montana (like Williams, Rosy, and Legi) to consider moving on a little more quickly, IMO.
