Welcome to December, that time of the fantasy football season when questions about whether weather matters become more and more prominent. I'll admit that if you're looking for someone to give you the best and worst schedules for the rest of the season in terms of how weather could affect performance, I'm not the person to ask. I'm sure you'll ask anyway, but more often than not my answer will be that it's largely irrelevant to me. If I can drive my car in it, then chances are a quarterback can throw in it, a running back can run in it … you get the picture.

Like many factors in determining who is and is not valuable in any given fantasy football week, I might look at two evenly matched players and break the tie for the one playing in a dome, as opposed to the one dealing with sub-zero temperatures and snow, but I also think we've seen plenty of instances in the past when players were able to overcome difficult conditions. For example, in Week 16 last season at Gillette Stadium in Foxborough, Mass., there were blizzard conditions when the New England Patriots embarrassed the "warm-weather" Arizona Cardinals with 47 points. Matt Cassel threw for 345 yards and three touchdowns, while Wes Welker made a snow angel (and eventually got fined)! Kurt Warner barely played in that game, by the way, and the Cardinals couldn't run the ball even in home games, so who's to say a blowout loss wouldn't have happened anyway? The Patriots had no problems.

I guess the point is keep an eye on the weather when it involves your players, but don't assume a snowy day means NFL teams won't be able to put points on the board. For those of you who have been asking this question for a few weeks now, planning ahead for your playoff matchups, I'd say it's unlikely you'll be making major roster changes on the chance snow will visit New England, Chicago or another place on a future Sunday, but when it comes time to make final decisions, consider it a potential tiebreaker. Hope that answers your collective questions! And if not, just ask Christopher Harris, Tristan Cockcroft, Matthew Berry and the others from ESPN Fantasy who host weekly chats! Or try the Answer Guys!
