I some what agree and disagree. Most schools are already negatively recruiting anyways but it's the schools job to squash that and that helps when you have a mega coach like Harbaugh. Like it or not he is popular and kids seem to like him. I think/hope the Harbaugh staff learned that they need to cut ties sooner if they're going to do it. Even though it sounds like all 3 kids were told in advance of not sure on the room and advice looking around. Urban pulled a commits scholarship last year in December, it happens just better timing having a month than kids reporting they had 2 weeks.
I truly don't see this effecting them though, they are pulling in high recruits right now and this is the highest time of criticism. As people know, time passes and people forget and forgive.
