No, but it’s actually an effective drill.
The idea is to build up the muscle memory into not immediately grabbing high when the ball is in play.
In today’s game they call P.I for **** near any contact, so as a DB coach you want to teach your guys how to have the least amount of contact as possible while still being able to make a play on the ball while reading the WR & playing through the hands to knock it down at it’s high-point or disrupt the WR’s ability to catch it & hang onto it.
People’s fan-first inclination will be to clown a drill like that, but Mike Reed is no dummy...
