The difference is in risk of other factors
Can you handle the increased spotlight?
Can you manage and direct increased staff (typically have to be a better delegator)
Do you know how to manage having unlimited resources at your finger tips?
Can you recruit?
That’s why many schools like to see proof in the pudding first
Is it really any different than a mid-major coach? You really don't know if they can handle it until they take the job, and have been there a few years.
If we had hires Bruce in 01 out od Southern Indiana, would that have made him a worse coach? No.
Either you can coach or recruit at a major school, or you cannot. Every hire is a gamble, and there is a bigger chance that you will eventually get fired, than have success.
But overlooking DII guys is really doing your program a disservice.
