Inappropriate use of GPS a reason for Packers injuries?

Maybe this guy has something to say, but that sentence is just gibberish.

Repeat the movement is the only part I think might join the two topics.

I took it to mean repeat the movement at full speed so when you're in the game its natural instead of something you have only gone through the motions of.

From whats left of my memories of actually playing football, hitting hurts. Hitting full speed hurts more. hitting full speed without having ramped up to it and practiced how to do it without taking the full brunt of the collision was a recipe for injury.
