"It's okay" t-shirts

[I was flipping through the Spark magazine at breakfast and pointed out to Brianna that the Women's Volleyball team at Calvin won the National Championship. Brianna is in 6th grade and is planning to try out for Volleyball at school. There was a team picture after they won where the women are all wearing t-shirts that read "National Champions".]

Jack: Look, Brianna, the team is wearing t-shirts that say 'National Champions'.
Brianna: But how did they know they were going to win? Or did they also have t-shirts ready that said "It's okay."?
