Shields resigned after spending 15 years as the head coach and 22 total years in the program in order to spend more time with his wife and three kids.
Under Shields the Trojans rose from the Eastern Maine cellar all the way to the pinnacle of high school football as the Trojans have reached two straight Class C North title games including one state championship appearance.
Despite never winning a state championship in his 15 years as the head coach, Shields feels his time at MDI was a successful one because of maturation and growth of his players.
"Those seasons are difficult in terms of those sorts of things but ultimately for me my seniors. Those relationships with them are more important, I told them that after the game. Our relationships are going to be much more important than any state championship," Shields said.
