Rain is projected for the whole game. What say you?
Does the ref wipe the ball off after every play if the turf is wet?
That sounds more like a deflatgate problem then a weather problem nowThe umpire usually does it, or maybe it is the new Center official.
They switch the ball or nearly every play now, so the ball boys on the sidelines will do most of it.
The rain will be over well before the game, don't worry about it
