Why does everyone think it’s a guarantee that the bills will have the final possession of the half? Whether they do or not has nothing to do with the coin toss decision.
I think it’s always better to receive first and to get the offense in rhythm. It also helps to see how the defense is planning so you can adjust for subsequent drives.
its also a helluva lot better to play ahead. Putting the offense on the field first helps achieve that much more quickly than the defense.
