I'll be pretty disappointed if Els is still here next year. His ability to develop linebackers is, well, questionable to put it nicely. And his special teams have been atrocious, to put it nicely.
I think our offensive line has improved by leaps and bounds over the last few years, but it's still not anywhere close to where it needs to be. I'm not sold that Garrison is the guy. I get the impression people are infatuated with him simply because he's not Barney.
I'm also not sold Barney is as bad as people make him out to be. But like I said, the line isn't where it needs to be.
You're right about Pap and Kaz, they should get at least another year. Pap was far too inexperienced to be named Defensive Coordinator in the first place, but he is an asset in recruiting, so perhaps it was necessary to keep him around? I don't know, but the defense needs to improve dramatically next year for him to earn a little more rope. Fair or not.
I'm a fan of continuity, so I'd be ok with keeping the staff mostly together. Aside from Els, I'd be pretty disappointed if we can't find an upgrade there.
