Jim Harbaugh is definitely 1 of the more interesting head coaches in college football with his signature khakis look. Former Stanford and current head coach David Shaw had an interesting comparison for what working for Harbaugh is like per Will Backus of 247Sports.

Harbaugh and Shaw were both at Stanford from 2007-2010 before Harbaugh left to take the San Francisco 49ers job in 2011. Shaw was named Harbaugh’s successor after working for him as the offensive coordinator and RB/WR coach. Since taking over in 2011, Shaw has gone 93-45 as Stanford’s head coach.

Here’s what Harbaugh’s former assistant had to say about working for him:

“My time with Jim, it’s one of those things like when you step off a really good roller coaster,” Shaw said. “You’re like, ‘Wow.’ That was exciting. That was scary. That was fun and I need to take a deep breath. That’s what working with Jim was like. Each day there was going to be something new, something different. Some things you’re going to question what you do. Some things are going to reinforce what you do. The biggest thing I take from Jim is making sure you have a competitive environment everyday. We’re always competing every game against everybody. That’s that mentality that I appreciate that I took with me and made sure that stayed when Jim left. We had different personalities. We do different things. But I always appreciated the competitive spirit that Jim brought everyday.”
