Our NBA Game simulator will take your input for adjusted or projected team score and will incorporate standard deviation of team scores, which is included, and spit out hundreds to thousands of game results.
You can change it to run as many simulations as you want. You can adjust standard deviation and then view all the results.
See how often each team wins, how they do against the spread and how the over under fairs. Plus this is in Excel so you can easily add more data to it.
