Your argument about the receiver having the footing is the same point DaBlueRaider is making regarding the running game. Both of them know where they should go, but their footing is would be tricky if it is raining. As far as the ball being dried off....you can dry all you want, but if it is raining, those balls get wet. Use all the balls you want..they will get wet if it is raining. Once leather is wet, it doesn't dry overnight. Wake up...
