So what does he do? He talks to them, of course. All in individual meetings. He keeps this Monday's victorious post-Orange Bowl press conference on point about the game and dodges other questions (as does his QB Andrew Luck) . So what's a guy-in-play to do? And here we have internet reporters searching for a story making stuff up.
It appears that Harbaugh doesn't want to go "back" to Michigan (too much headache and problems there). He entertained the Dolphins because the owner is a major Michigan benefactor (and he was on the sideline at the Orange Bowl) - and he had an extensive five-hour talk with San Francisco - well because its the 49'ers, and its right up the street from Palo Alto.
What is clear to me is that Jim is now a California guy - once it gets in your blood its hard to get out. He can now stay at Stanford (now that his 2010 draft rated number 1 QB is coming back for his junior year) and make a run for a national championship - or have a great year, nonetheless (and get a handsome raise). Or go to the 49'ers - but now that Luck is staying at QB, and he's tired of all of the blah blah pro pitches, I bet he stays.
But anyway you look at it I don't think he's leaving Cali.
