I'm so tired of the "turn your head" crowd. I've posted on here before from great pro defensive coordinators. They are taught , IN THE PROS, to not turn your head for many reasons. This is coming from Belichick among many others. It's called being in phase. They are taught in many instances to play through the hands and to not look back. Of course, there are guys that can do it and do it well. Usually those are above average, very fast DB's, and are coveted for their ability. Not everyone has that or is it possible to do that all the time. Obviously to most people but not obvious to all apparently, you run slower with your head turned around. Again it's taught this way all the way up to the NFL. Simply saying "turn your head" is not, in most instances, the way the players are taught. If you watched the Super Bowl, you saw guys who did not turn their head around. You even saw the one guy who did for the 49ers on the long pass from Mahomes, he got turned around and the ball was thrown over his head for a very long completion
