I'm not a big fan of co- coord either but look at which one gets paid more and that's your actual OC. Dabo is helping someone on his staff get a chance like he was given. That's all and it's admirable. Dabo isn't gonna give the reigns to someone incapable . You guys can all relax. These guys have been talked to and they know who is in charge and they work together already.
To add to your sentiments, you can bet this has been a Plan B in place for some time. It maintains continuity, as the lack of it in coaching changes very often damages a program. For this to happen quickly, I'm betting that Jeff has been groomed for quite a while in anticipation of the eventual promotion of Chad to head coach.
There is one other aspect of this that I learned in business a long time ago. If you are performing your duties at a high level, and your employer does not recognize it via a promotion when applicable, some other employer will.
From everything I have seen from Jeff Scott so far, I want him to continue to be on my team's sideline.
IMHO, very well crafted. Now let's go win a bowl game.
