Being a football coach doesnt really have a direct crossover comparison to working in corporate America.
Do you think its a 1:1?
Yes absolutely. Especially at this level. (SEC) This is a billion dollar industry, it is very similar to corporate America...
Yep, thats why they write Non-compete clauses into contracts. doesnt seem like Ole Miss did that. again, back to OM's fault.
Coaching contracts have a non-compete in them, but thats not what Kiffin did. If he violated a non-compete he would be fired with cause, which would mean Ole Miss doesn't have to pay him another dime.
At the end of the day OM didn't believe that he could effectively be their playoff head coach while also having the responsibility of another (Rival) team's head coach. Ole Miss offered him the world to stay in Oxford and he declined, their only other negotiating power they have is to remove him as a coach.
I'll summarize, - if you are leaving you job in 2 months for another job in the same sector you will tell people or you will keep it a secret. If its a secret, wouldn't you feel bad bringing on a new client(establishing a relationship) knowing you will be leaving soon? If you tell your current and prospect clients, and they like you, wouldn't they be inclined to switch their business to you when you start your new job? I shouldn't need to further clarify the similarities between this scenario and a cfb coaching job, but maybe I will.
