In my opinion gambling has ruined sports. Having "skin in the game" can be fun. Cheap or silly friendly bets among friends might raise the interest in the outcome. But supporting the multi-billion dollar gambling industry where the house ALWAYS wins? Nope. Not for me and I hope the addicted can escape.Unless you have a bet on the game who cares? (do people actually bet on pre-season games? THAT'S gambling addiction!!).
The saying about selling drugs applies - don't use the product. That is what the gambling industry is doing. Selling something where they are literally guaranteed to win.
