When hiring a coach from a lower level program or conference, I’m not a big believer in “If he is doing well there, imagine what he would do with the resources here.”
Coaches struggle to change what has worked for them that helped them land the job. With that, the floor of the coach is common - he builds a product similar to what they created in the previous job, which doesn’t work in the new place. See Hugh Freeze at Auburn, Billy Napier at Florida, Troy Taylor at Stanford. I think Fickell is on this trajectory as well. The ceiling is less common - the coach generates a similar W/L record at the new school (Rhule and Fleck). Then there is the very rare case when someone to moves up in class and actually improves the W/L record, but it happens (Cignetti and Elko).
So regarding Mora, his floor at Rutgers would building a team similar to today’s UConn, but competing in the Big Ten – that would be a disaster. His ceiling would be the 9-4 record he got last year. I think he would be closer to the floor. Not saying I love GS, but if you have a problem with him Mora is not the answer.
