I've never even been inside of a dome. I've played football in a basketball gym, but never basketball inside a football arena.
This team is probably the loosest I've played on. Coach does a great job of keeping us loose. We play baseball at practice. He dances, claps, sings, and we all rally around that. There was no tension around the team.
