I want to point out few things... As long there is someone to catch the ball, it doesn't matter if it's high, low, away.. as long receiver can catch the ball whether they are standing there or running. I promise you, it was just first day of spring practice and we have a new OC who possibility was running a new drill that we may not notice in the first place. You're reading way too much into the practice video than it needs to be. Look at any practice video with another team and you probably will see the same thing.
