This isn't the official H&R pool, but if you're interested in joining my personal pool, here you go:
Usually I get 125 people or so, but I'd love to increase that with all my H&R friends! Scoring is based on my points per round mulitplied but the team's seeds. This rewards picking the tougher first round games correctly (8/9, 7/10, etc.) as well as any upsets throughout the tournament. All of the rules are on the site itself, but you can let me know if you have any questions. You can enter as many times as you like!
