I know you're trying to be a smart alec here, but the answer is yes...sort of. I have no problem if a Buckeye fan said something to the tune of "Urban was able to build off of, and keep going, what Tressel did and we owe at least some of that team's success to the great job Tressel did laying the foundation it takes to keep winning at a high level".
My point is that Riley may have recruited the players, but it was Erickson's coaching that got the Beavers to 11-1 record winning a share of the conference title and a Fiesta Bowl win. Just like it was Urban's complete control of the Buckeyes that got them the title.
