I am suggesting his inability to retain staff at the position coach level is a major reason why the play has been so subpar going on three years now with this season being the absolute worst.It's pretty simple isn't it? You can't promote everyone! So either every single guy ends up being the offensive or defensive coordinator or they leave, that's just how it tends to work.
Alabama coaches rarely leave for lateral moves, but at the same time every coaching position at Alabama is filled by someone right? Is the solution to every single departure to just promote from within?
Part of the problem is Saban has strict limits on his coaching staff size at Alabama, so he can only ever offer a finite amount of spots. However, all the other coaches out there, including former Alabama guys who are head coaches now (Kiffin, Sark, Smart, etc...) have an equal number of slots.
Just do the math, there will always be more room to move up outside of Alabama than within the staff at Alabama. There's no way to even remotely address that without the NCAA allowing Alabama to retain as many coaches as they want. Then, in theory Saban can go ok, Alex, here's an on field position because we really want to keep you around.
But, just consider what happened. Alex went from an analyst for several years to offensive coordinator at UAB! Are you suggesting Alex get promoted to offensive coordinator at Alabama after never holding anything higher than wide receivers coach at a semi-pro team?
You just can't do anything about that went there are dozens of coaches out there looking to poach Saban's staff and you can't even open up more on field coaching positions due to draconian NCAA rules.
I am also suggesting that several of these guys left for lateral moves. That has not been "rare." As a position coach if you are not leaving for a coordinator role, you're not taking a step up by leaving Alabama.
That's my opinion.
