OK - let's say the coach is the problem.
so MN just needs to find the right coach. A coach who will willingly agree to come to MN under the current circumstances.
being honest - MN is a program that has not been relevant in the conference, let alone nationally, for 25 years under multiple coaches. now, you add in the portal and NIL. and you add an 18-team conference. MN may be a member of the B1G - one of the more powerful conferences in college sports - but in basketball terms, MN is just not relevant.
So all Coyle has to do is find the right coach who can cope with all of that, and make the program relevant.
Oh - and MN has to be willing to pay a salary that will make that coach agree to come to MN, knowing all of the challenges it presents.
"Hire the right coach" sounds simple. It's not. It's easy to type on a message board. it's a lot harder to pull off in real life.
