Pretty cool. My random thoughts/feedback:
1. Good mix of easy (Marino signature) vs difficult (name that brand) questions. Would like to see what the average rate of correct answers are for the participants.
2. Had mostly baseball and football questions in my set. Any basketball? Hockey?
3. The 'card' questions focused on the front of the cards. Don't forget the back of the card. Perhaps some trivia around famous stats (or stat errors) on cards?
4. Overall, it was fun and would do it again.
