Jim Harbaugh brought in a coaching staff from all corners of the country when he was hired as Michigan's new man in charge back in December.
The staff is made up of men who have coached all the highest levels of football. They could have had jobs anywhere, but chose to work for Harbaugh, who's personality rubs off on those who spend time around him.
"Jim is a tremendous competitor, you don't find a guy who likes to compete like him and he's got tremendous respect for the game of football," he said. "It just kinda leaks over to you by being around him. Infectious.
"He just wants to win. It's fun, it's a fun time. It's great because it brings the best out of you, it's like when you walk in every day, you have to be on your A-game and just even as a person too, being a great father, a great husband, and he does the same thing. We owe it to our children and owe to our wives.
"You want to do it and that's what he does, that's the uniqueness about him. He's got tremendous fuel within him, has a real good gut check on knowing what's right and what's wrong."
Drevno is tasked with coordinating operations on the offensive side of the ball, as well as working with the guys up front. It is a unit that has struggled in the last few years, but he is confident and believes in what they have there.
"I feel really good going into training camp," he said. "I think those guys have a nice spring and good offseason in the weight room. I want to see us get better everyday, fix a problem, take two things and fix it and get better everyday and we'll be on course."
What the offensive line is able to do is one of the keys to the offense this season, and Drevno knows what his guys have to do.
"Everyone knows it's about the offensive and defensive line and quarterback," he said, "If you got those three things, it makes your life a lot easier. Not saying the other positions aren't important, but it is one of the lightning rods of being competitive and successful."
