Perhaps the XFL will tighten the reins just a bit on this element going forward just for the sake of fairness and to prevent stuff that ultimately hurts the product and leads to the league folding.
The level of sideline access in the XFL is unprecedented in professional football, and one won’t hear a coach’s detailed play-calling nearly as much if at all in collegiate or NFL games.
This might be why the coaches were shocked by just how much and how often it happened during the first week of games, and why they may make changes to their plays going forward.
