I've got no problem with Bo speaking with other schools.
First, it's just something that is done in the business world. It doesn't mean you don't like your job, you want to quit or you're afraid of being fired. Many times it's simply a networking/experience building exercise.
Coaching is all about who you know...and just because you have a job today, doesn't mean you will a few years from now.
On top of that, the more ADs Bo knows... the more coaches jobs he has connections to should he want to help out one of his assistants.
So, if Bo is out talking with ADs... building up his own HC credibility within the AD community, he's doing it to better himself and put himself in the position to help those around him.
I'm the glass half full fan, and I'll assume the best in these type of scenarios.
There is certainly to glass half empty view of this, that Bo speaking with other ADs is him trying to get a better job and ditch NU - but that's just too cynical a view for me.
