From this weekends Rivals Camp Series, Nashville. Stephen Herron asked to update his recruitment status.
-Michigan calls him once a week. He is still committed to Michigan. Will make an official visit some time in summer.
-Stanford has flown to see him 10 times in the last 3 months. Calls him at least 3 times a week. Is he going to make an official visit to Stanford? "I would say so. Yes."

It's clearly sounds like his committment is not secure, is seriously considering Stanford, and could still flip there.
