Dan Sherman was only 36 years old, and his death Tuesday has been a total shock to everyone.
He was an assistant coach for the baseball and football team at the Medina High School.
Teammates and coaches say he was not just a great coach but a great man.
"He's just one of those people in life you can't really replace in life," said Zeke Martin, who's on the football team. "He was one of the greatest coaches. I've learned so much from him."
The school district's athletic director says Sherman died Tuesday during a workout.
The head coach of the baseball team was rocked by the news.
"It was really tough ... a sinking feeling 'cause ... I know the family really well," Nick Kaplack said. "He has a lovely wife, two kids that he loved very much."
The football players he mentored as tight ends coach are rallying together.
"I feel like I lost a big part of my life," said football player Collin Minor. "Me and Sherm were really close. He was my baseball coach as well, and football. He's been my coach since eighth grade."
Grant Hight, an outside linebacker agreed.
"He was my coach. He was my neighbor. He was my friend," he said. "I lived right by him. He was a great man. … Everything he did, it was always people first before him."
The fifth-graders at Waite Elementary, where Sherman taught, are also showing some love for him.
And the community is already raising thousands to support his family. An online fund was already nearing $30,000 Wednesday night.
