I remember the 2020 playoff game against Baltimore with the crazy wind. I thought it would favour Baltimore as they were the better running team, but it didn't.
The bills stacked the box and made Lamar beat them and he couldn't.
Lamar is definitely better now, but I think the same principle applies. If the weather is bad, Make them one dimensional/take away the run. And we have a cheat code at QB who can throw in anything
