The key with weather and football, for any position, is avoid extreme weather, regardless of position. High winds are the biggie, but also heavy rain or snow, and let’s not forget heavy fog! When you get into extreme weather, all the teams can do is run the ball, over and over. If it isn’t too extreme, they can throw short passes. Regardless, it cuts down the options, and makes the game low scoring. Avoid all players in those games!
Yahoo is actually pretty good about putting up weather forecasts in their fantasy football screens. Just scroll over your player’s weather icon and get the forecast. If you still aren’t comfy, check out the National Weather Service’s forecast for that area: https://www.weather.gov/
