Buffalo Bills to Interview Ron Rivera for HC Vacancy

This from the S.D. Union-Tribune Twitter:

REPORT: Buffalo radio station cites source saying Bills will seek to interview Ron Rivera. Could happen next week, during Chargers' bye.

NOOOOO!!!!!  The first thing that jumps in my mind is that a team without distractions suddenly has a big one.  The better the defense plays, the better chance that they have to learn a whole new system next year (when I believe they'll all be back).  That will be the third new Defensive Coordinator in four years for the Chargers, which is partly a good thing (two will have left to become Head Coaches elsewhere) and partly a bad thing (how will the players ever get comfortable?).

The second thing that pops into my head is that this is valuable game-planning time, and instead of being in meetings with his defense Ron Rivera will be traveling cross-country and thinking more about his salary and the glory of being a Head Coach instead of focusing all of his time and energy on possible opponents for the Chargers.  Maybe since the Chargers won't know exactly who they're playing the following week it's not such a big deal, but I don't like the idea of taking time away as a Chargers coach to play with the possibility of being a Bills coach.

I also see this as a bit of a Rooney Rule interview.  Head Coaches in their first season deal with enough transition as it is, but forcing Ron to try to switch a team with 4-3 personnel to a 3-4 defense on top of all of his Head Coaching responsibilities just seems a little insane.  Has anybody else ever been hired, switched the new team's defense from a 4-3 to a 3-4 and called plays for that defense with any sort of success?  The Jets already had a 3-4 last season.  Maybe Belichick, I'm not sure what the Patriots were doing before he got there.  Either way, it seems a monumental task in a town that's already impatient and looking to keep it's team out of Canada with a winning season or two.

Let's hear your thoughts in the comments.
