We see Edmunds. It’s about blocking lanes and balls thrown across the body from Mahomes. You’re basically just backing up to take away angles kinda like playing tennis. You find the spot on the court where you can’t get beat down the line or cross court but can still react and back up for a lob.
If Edmunds sees it’s a run, he can approach the net the same way you would serve and volley. If it’s a pass, you back up and protect those same lanes and don’t let the ball (player) get past you.
