Gameplanning isn't something that's done in a film session or the week of the game. Most coaches have a philosophy that they employ and believe in and have a method of playing against all different kind of teams. I'm sure Schemedding and Graham have talked for hours on end about how to best stop a triple option. It doesn't always mean they have the answers, but they have an idea that they can implement to adapt the defense they run to the offense they face. Just the same, I'm sure Baldwin and Best have talked a lot on how to attack a 3-4, 4-3, 4-2, or 3-3 and how to get after all different coverage types.
I remember Coach Zornes going to and even hosting several conferences to talk about how to use different strategies. These coaches are, by and large, pretty damn good at what they do. Football is a far cry from soccer, for example, where you basically put your best 11 on the field in the formation that best suits them and let go at it for 90 minutes.
Wind is probably something of an on-the-fly thing to adapt to. I can't address this issue specifically, but I'd guess they know all the plays that are less likely to be impacted by wind like the back of their hand.
