But it could have played out another way. It could have been too much to overcome - the mediocre record, the disappointing finish in the division, the snub from the Diamond Classic, the road games in the sectional tournament, Comer's lack of action through the first six weeks of his senior season.
"These guys understood there were going to be ups and downs in a baseball season," Cassel said as his players celebrated the state championship on the field at Toms River East. "They realized they needed to play with a sense of urgency when it got to one-and-done."
Cassel is The Inquirer's South Jersey coach of the year in baseball not because his team won the state title. He merits the award because he guided his team through those ups and downs, helped the players gather that urgency, and never compromised on his first priority as an educator.
"He keeps us safe and protected," Comer said. "He treats us as people and not just as baseball players."
This was a tricky season for Cassel. Comer, the hard-throwing senior righthander, was projected as a high pick in the major-league baseball draft - which meant a lot of money was on the line.
Comer also was hurt for much of the season. It was nothing major, a sprained ankle, a sore side, an illness. But it greatly complicated the situation.
More than a few coaches out there might have put the team's interests ahead of Comer's interests. More than a few coaches might have pressured the kid to pitch a little more, to tough it out for the team.
Cassel didn't do that. Comer pitched just 13 innings through the first six weeks of the season. He was 1-0 and Seneca was 9-6 on May 20.
But there was another side to the situation: the rest of the team. The Golden Eagles were a senior-oriented squad, with high expectations. They had to be frustrated not to win the Olympic Conference National Division, not to qualify for the Diamond Classic.
Cassel had to coach the rest of the team, too. He had to keep the Golden Eagles together through a rough patch that included five losses in seven games before the start of the state tournament.
