I don't think this would mean the portal wouldn't be a big part of the program. But programs that don't have the high NIL budget, this has to be the way. Recruit, develop and portal. Create a program where players largely want to stay. I think that is where it is right now. Lots of guys could have left for more money but chose to stay. Then use the portal to fill in the gaps where needed.
Focusing on the portal year after year with limited NIL is not sustainable IMO. The top programs with the big bucks can reload every year through the portal. Minnesota (and almost everyone else) cannot.
