Born in Australia nearly 23 years ago to parents who never married, his dad, Roy, left with him right away and headed back home to the United States.
A year later they got a phone call. Long distance from Down Under with this message: Mike's mom, 29-year-old Diane Brooking of New Zealand, who never wanted to move, had been killed in a car accident.
That's it. Hermann and his dad still don't know what happened, probably never will.
"It was a rough childhood," Hermann said. "There were women always coming in and out of the house. I never really had a mother-type figure until eighth grade."
And he never knew where his dad, a self-employed car restorer, was going to move next: Georgia, South Carolina, Florida, Alabama, Pennsylvania, New York.
"He kept moving for no reason," Mike said. "It was very difficult. I'd get comfortable in a place after a while, and we'd pack up and leave out of the blue. I met a lot of people, I've experienced a lot of different things."
"The poor kid got dragged around," said Hermann's aunt, Estelle Nadel. "He never knew where he was going to be."
Thanks in large part to his dad, a mountain of a man who once played semi-pro football in Australia, sports became an outlet for young Mike. He excelled as a catcher in baseball, but while playing junior varsity in Hilton Head, S.C., the football coaches spotted him.
"I had a good arm," Hermann said. "They asked me if I wanted to play quarterback. I thought I'd give it a shot. At the very beginning I played for the fun of it. I was more of a baseball player, but I grew out of baseball. It was too slow for me. A lot of sitting around and bad on the knees."
Roy Hermann pushed his son to greater heights.
"I learned that in order to be successful at this you actually have to want to hit people," Mike recalled, not knowing he'd soon feel the urge to do just that to his dad, too.
By the time he turned 17, the arguments with his father, who had contracted a debilitating form of dementia, became too frequent and too heated, so Mike divorced him.
"My dad's illness has unfortunately messed up his brain," Mike said. "We were on the verge of killing each other. It was in my best benefit to get out of the house."
Legally adopted by aunt Estelle and her husband, Steve, Hermann ended up in prep school at Avon Old Farms in Connecticut and became a captain. Despite earning player of the year and All-New England honors, dreams of playing college ball seemed remote at best.
