You can compare what actually happened with what he said. From another article with more info on that:
A divided Supreme Court ultimately ruled that Kennedy had a right to pray under free speech and exercise clauses as long as he wasn’t coercing others to join him.
After the ruling, the district wrote a policy that allows coaches to pray while not actively supervising players if the coaches keep their distance from students when the prayers begin. After that, students can join if they choose.
“I can’t tell them to or not to,” Kennedy acknowledged last week. “If they want to join, cool. If they don’t, cool.”
No students did so at Friday’s game against the Mount Douglas Rams, from Victoria, B.C. A larger-than-normal crowd suggested Kennedy’s supporters showed up, but none stormed the field to join him in prayer, as happened at a 2015 homecoming game. A scattering of applause accompanied the coach’s kneeling at the 50-yard line.
Kennedy quit his full-time job at the Bremerton shipyard before moving to Florida. With his newfound celebrity, he has a promotional website, a book coming out in October and a movie about his life in the works. He speaks to political and religious groups, and says politicians including Republican presidential candidate Ron DeSantis, Florida’s governor, have courted him for his endorsement.
