The fumble minigame features a goof where it swaps the panels of the buckets to reverse the outcome in the same way the penalties do. PTD is in active development and some things are subject to change, and it's likely there will be a more obvious visual joke or skit to go along with it.
I'm glad you enjoyed playing and shared your thoughts with us!! It'll be a few months until release, and we look forward to sharing more teams, powers, and goofs with you when the time comes :)
