Harbaugh had a chance to come in and make the same type of recruiting statement and failed huge. And as
@Buckeyes86 posted above, David Shaw has recruited better at Stanford than did Harbaugh. As for the "Michigan brand name", it sure the fuck didn't help them for the 2015 class, now did it? It took him over three weeks on the job before he got his first commit, and of the eight commits he got for the 2015 class, only two were 4* (QB Gentry, and TE Wheatley who happens to be a legacy recruit). So, no, he's not a guarantee to get a top 10 class next year.
