Depends on the optics to better understand state. If you are younger than 35. Then this surely looks like a short run aka similiar to other schools striking it rich when some of the stalwarts are down.
I really believe as long as we have alignment in the leadership at the President, AD, Booster, and Coach level, than this type of run is possible. MSU had that alignment for its first 60's years of its program when they were fighting to become a university and a Big 10 member. They lost their way for many years, albeit with some success with Perles, and a year or 2 with saban.
Our biggest challenge is that Michigan does not produce the high level of talent to field one let alone two Power 5 schools. Thus, we are forced to recruit heavily in ohio, pa,nj, and now Ga, FL.
I feel confident in the future, and should be very interesting battles once PSU and UM right their ships.
