The whole crux of the issue is that Harbaugh hid behind Stanford's academics and admissions in various ways, all that were to his advantage and bad for high school kids. Harbaugh would blanket offer kids the week after Signing Day, literally sending offer letters via fax to hundreds of kids. He would then accept the commitment from almost any player who would give it to him before hiding behind academics/admissions if he felt he could fill that spot with a better player.
If two kids had substantially equal academic profiles, the high-profile recruit with multiple BCS offers would get his admission decision in September or October while the low-profile recruit with only a handful of offers would be told that he wouldn't know before late January at the earliest. What else is a kid supposed to besides consider other options while they're still viable? A kid who had numerous offers early in the process might have none left at Signing Day if they're taken by others.
And it's not like Stanford was turning away guys with poor academic profiles. I'm not going to publicize kids' academics unless they've done so themselves, but
Daniel Davis is a prime example. He was told that he wouldn't be admitted despite carrying a 4.0 GPA and 29 ACT. He eventually landed at Penn. Kain Colter had a similar academic profile.
There was a story making the rounds of a kid who attended a Stanford recruiting event with his offer letter in hand. He tried to commit to Harbaugh in person, but his commitment was refused. This was a kid with multiple BCS offers that ended up as a starter in the Big 12, so it's not like he couldn't play. Harbaugh just decided he didn't want him anymore.
It was the same thing with commits who stopped getting any kind of contact from the program. Do you really think that Stanford would have sent these kids a Letter of Intent for them to sign? They would have been left without a destination after 99.999% of available scholarships were filled. Not exactly an envious position.
We had high school coaches calling our offices literally volunteering to help us recruit against Stanford by sharing their Harbaugh horror stories. I had a list of their contact information on my desk in case anyone asked.
It was bad.
