I have a made a couple of boost parlays with a player's total dunks and the team to win. I had a bet on Lebron James over 1.5 dunks on Saturday and Lakers to win. I didn't watch the game but I know Lebron had at least one dunk because it's shown on a game highlight that I saw. Somewhere there has to be official stats. Otherwise the book has to watch the full game and record the dunks.
