The odds last time I checked of the Lakers winning the conference was +130. The Spurs was also +130.
Let's be honest, ONE of those teams will win the West no matter what. That's a guarantee.
Put money on Lakers +130
Put just as much on the Spurs +130
And if one of those teams win the conference, you get a 15% return on your investment. You can also adjust this rate by maybe putting more on the Lakers or Spurs, so you can get a 20% if Lakers win and 10% if Spurs win or something.
For those who just want to make guaranteed money and live in peace, just put your entire bankroll on this and enjoy the rest of the NBA season.
