To me, its not about "the guy". And as many here have said, a successful guy may be gone again in a year, and we do this all over again.
Its about "the system". This year, we had a very successful system, one that was well suited to our players' strengths. I'd like to see that system continued regardless of who the guy is. I don't want our players to have to learn a new offensive scheme in the spring, having to learn the new guy's terminology, etc, and possibly trying to make a system work that they're not really built for.
Continuity is important, and we can have it if the new OC is a flexible guy who doesn't insist on imposing 'his system.'
Tim Salem is the obvious choice to accomplish this. He's been an OC before, so he has experience. I don't know what PN thinks of him as a leader at the OC level or his play calling ability, but if likes him in these regards and hires him, I'll be very happy.
Some of you will of course, criticize the hire as a cheap in-house option, and be disappointed that we didn't get a big name guy...for one year. I won't.
