I hear on WGR this morning that the last time the Steelers played in Buffalo (2022) it was extremely windy, though not cold. The Bills smashed Pittsburgh that day and the passing game was on point.
I don’t think weather will hurt either team with what they want to do. And, to be honest, the wind can be blowing one way one day and another the next so I’m not so sure it would make that much of a difference practicing in it.
