For real. He's actually a non-posting member of their Rivals site (although, all the writers switched to Scout, so he's probably a member there now). He has openly admitted it.
As for that interview, I don't know how anyone can listen to it and not come away thinking that there is something off with Harbaugh. I had a minute yesterday and and went over to mgoBlue for the first time in eons, and it was crazy how many embers were spinning it as if it was all on Cowherd. WTF? Yes, the "buy/bye" question was not a good one, but Harbaugh comes off like he's got some social disorder, as Wooly and others said. Those weren't difficult questions...coachspeak 101 gets him out of there in a cool 5 minutes smelling like a rose.
Won't hurt him once he starts winning so it's not that big of a deal, but it was a head-scratcher for sure...
