Without more, I’m actually inclined to believe that it was a mistake.
1) Athletes and coaches (especially football players/coaches) thank God all the time. Why would they choose THIS time to engage in some sort of censorship?
2) Live sports and live interviews are broadcast with a “seven second delay.” If they wanted to cut off the mention of God, why did they cut away AFTER, not before?
Agreed. Sometimes a break in transmission is just a glitch.
