Andre Patterson was 27 and fresh out of the high school coaching ranks when he met 31-year-old Mike Zimmer at Weber State in Ogden, Utah, in 1988.
The Wildcats were coming off a 10-win season and a trip to the Division I-AA quarterfinals. Zimmer was heading into his fourth season as Mike Price's defensive backs coach. Patterson had just been hired to coach the defensive line.
Similar in thought yet different in approach, they hit it off immediately.
"We have a common bond that we both strive every day to be great, and we both strive every day to try and overturn every rock that we can to put our players in a better position so they can succeed," Patterson said earlier this week when he spoke to reporters for the first time since having co-defensive coordinator added to his duties as Vikings defensive line coach.
"From the first day we got together at Weber State, I think that's the thing that we both looked at each other and said we're pretty similar."
And yet they can be oh so different. So different that Patterson was asked to explain how they manage to work well together?
"You've heard of good cop, bad cop, right?" said Patterson, who joined Zimmer with the Vikings in 2014. "You know, I think it's like that. There's no gray with Mike Zimmer. There's no gray. You know where you fit. He's going to tell you, whether you want to hear it or not, he's going to tell you the truth of what you're doing good, what you're doing bad and what you need to improve on.
"I'm more of the motherly type. I'm going to put my arm around you and teach you just like I did when I was a teacher. So I always use the analogy of if I was a math teacher and you were having problems with something, I wouldn't stand by you and hit you in the back of the head and cuss you out. I'd pull up a chair and sit down and show you how to figure out the problem. That's my philosophy as a coach."
