Jim Harbaugh officially announced on Tuesday the addition of of his oldest son Jay to the Michigan football staff.

Jay Harbaugh, 25, will coach the tight ends and serve as assistant special teams coach for the Wolverines. After working as an undergraduate assistant for Mike Riley at Oregon State from 2008-11, Jay Harbaugh spent the next three seasons on his uncle's staff with the Baltimore Ravens. 

"Jay gathered a wealth of experience the last three seasons coaching in the NFL and I am excited to have him join our coaching staff," Jim Harbaugh said in a statement. "His passion for teaching the game is at the highest level and he will be an asset to our team. He did a phenomenal job in Baltimore and will do an excellent job mentoring our tight ends."

Jay Harbaugh has only officially been on staff for a few hours, but he is already sharing Jim Harbaugh war stories with the Michigan media. In a video on the school's official website, Jay Harbaugh told fans what happened at home when there was no milk for their cereal

"This one time, I was a kid and we didn't have any milk for cereal, and he put Gatorade in his cereal instead of milk," he said. "It was the weirdest thing I ever saw."

Jay Harbaugh was laughing while re-telling the story, but gathered himself enough to wrap the tale with a lesson in a very coach-like way. 

"That kind of says a little bit about him," he said. "Just gets the job done. Doesn't really care what it takes, not picky."

Michigan also introduced Mike Zordich as a secondary coach, joining Greg Jackson at that position. According to the Detroit Free Press, only a few staff positions (offensive and defensive analyst, player development, recruiting coordinator) still need to be filled.
