How do you expect to learn if you don’t play?
What I mean by this is, if you spend all of your time practicing throwing or practicing running plays or practicing catching, how are you actually going to get better?
Of course your skills will be better. You’ll learn to throw further and more accurately.
You’ll learn how to run the vertical stack better than any team out there.
You won’t drop a disc.
But what happens when you finally play a game and just as you’re about to huck, a defender steps in front of you and distracts you from making a perfect throw?
