I find comments like this unconstructive, and they always surface when people present forecasts. It's easy to play the shoulda-woulda-coulda game with data. "You should account for the breaking strengths of each team's players' ACL tendons. It could affect the outcome if they get injured!" Okay, so what? Did you do it? Does the data exist? Do you have any quantitative evidence of a statistically significant link between the weather and team performance? If you do, do you also have the evidence to show that the game forecast is not rate limited by the error of the weather forecast?

I'm not saying you have to write a thesis to suggest new data sources, but I am saying that "you need to do XYZ" is not a productive piece of advice without the evidence to back it.
