Michigan head coach Jim Harbaugh has been plenty active on Twitter since returning to the college ranks, and occasionally he likes to needle his old team. I don't know if this was meant to be trolling, but Harbaugh tweeted about this old Bailey 49ers anthem. I thought it was a pretty great song, but obviously it became just a little bit dated once Harbaugh departed the 49ers. Thanks, Jim.
Hey Bailey, I've got a question for ya! https://t.co/VyejFU7iPY
