Where can I find a list of players going to play or likely to play in a game

Question

Hi,I&#x27;ve developed a model that performs fantastic in back testing but, for lack of a better term, sucks in live testing. I drilled down the issue to the fact that I only fed the model the players who actually played in the game versus the team&#x27;s full roster.  For example, the Brooklyn Nets have 17 players on the roster but last night only 10 players actually played in the game. Is there a decent source for this information? Rotowire has "expected lineups" but afaik they only include starters. I&#x27;ve been thinking about creating another model that predicts if a given player will play in a given game or not.

I was able to solve the issue by creating a model that predicted if a player was going to play in a game or not. At first the accuracy was 82% but then I was able to get it to 95% by scraping the nba injury/suspension data from the prosportstransactions.com database. The model is back to performing fantastically!
