Here is my answer:
IF, and IF isn't happening, he could recruit players to about 70-75% of the talent level of the factories, his system would probably give us a chance in every game against any opponent, but unfortunately, I don't think he can recruit to that level with the academic rigor, restrictions and his own system's negative perception.
He seems to be trying now to overcome a talent gap of 40-50% against the better BCS teams, which is too much, even for his system. I will agree that the gap with VPISU is less than this, but Bud Foster kind of makes up for that.
That is my answer...Just my opinion though.
