This isn't a matter of groupthink. You asked a dumb question, people called you on it, and you're trying to pass the buck. That's what it comes down to.
In any case to answer the question, the reaction you've gotten is because it's not even close. Richardson has probably the biggest national profile of any of the in-state kids and should also be a challenge to land (Cass Tech aside). That said, Michigan is in a good position and there's never been anything that I've read or found suggesting he was interested in OSU (unlike Ross who was coveting an OSU offer).
It's too early to tell one way or the other but this shouldn't have any bigger impact on our chances then his Bama offer, or his USC offer or the ND offer, etc.
