NBA is such a joke.

All these teams that all of a sudden give up large leads in the final 2-3 minutes is a joke because the team that has the lead refuses to play defense at the end.

Might be something to consider with in-game middles. 
but yes, I’ve noticed this many times. I pay more attention when I have the fave, but the point shaving in some of these games is ridiculous. Players missing dunks and multiple free throws in the last minute to keep a game under by the hook. Turnovers, pace, lack of effort.. the absolute worst is when the game goes over the original total and then you see the players give up after, to keep the game under the closing total 

it is what it is. If you’re going to continue to wager, don’t be surprised by any result.

I think even newer recreational gamblers see what is happening, but we all continue to bet. Find the right game where your handicap matters
