Well you could just as well cite Northwestern's commitment with their new stadium being built for hundreds of millions and say, "Hey look, they are investing hundreds of millions in their program. We should do the same" and ignore the other details surrounding that investment. The details matter.The details are irrelevant to a certain extent. Otherwise, we could offer a coach $12M but if the details to reach that $12M are unattainable, it doesn't matter.
What matters is, they've committed to a realistic $9M a year, while Purdue was in the $4 ballpark.
I suspect Purdue will be in the high 6-8M range for the next hire, especially if he's coming from a P5 school.
