Just plugging my favorite yearly NCAA pick em pool. I like the format of this one better than any of the others that I've done. And while I'm all for charity, I like that most of the money goes to actual payouts in this one ($22 per entry, $2 goes to the guys that run it).
Pick one wrestler for each top 16 seed, and four from the remaining seeds, no limit to how many wrestlers you can pick from each weight, highest scoring teams win. If you can run a google doc and have Venmo or PayPal, pretty easy to get set-up.
