I’ve been thinking about this too and have been wondering to myself, what traits, skills or abilities, or game strategy beyond the obvious - run the ball - are good for football in sloppy, cold, snowy, stormy weather. I’m really not sure. Only universal thing I came up with is big hands on the offensive skill position players to hold onto a slippery ball, a strong armed QB and an offensive line that can block for run and pass. What else is needed?
