Looks like the sports gambling wall has been torn down and most states will probably be taking action pretty soon. NJ has been fighting it for 10 years and they are ready to go. You should be able to place a legal bet in a week or 2.
Can you imagine having action on PennState/Ohio State dual or any D1 Dual, Future bets on who will win tournaments (individual and team) or an over/under on a dual outcome. There would be tons of money wagered on NCAA Wrestling and it would bring great interest.
On the other hand I understand people that will want to keep the sport amateur and have nothing to do with gambling.
