I think this is a good point, however I feel we're also not accounting for any type of tweaking in terms of the offensive style that might allow for TOP to be more SEC-ish.
The example I keep thinking about is when Florida hired Meyer, most thought his offense was too non-SEC to actually be successful, let alone win championships.
If CJH is successful here, it will be because he is able to adapt his offense to something that works in the conference. I don't think the DC search is a matter of not being able to succeed with CJH's offense. I think a lot of the delay is due to timing between when we made a move, and things like NSD, Super Bowl, and now the FBS season starting. It truly is an unprecedented time to be making a move most we're expecting to be 'normal'.
