Speaking of middle screens, I had a play last week where I could've been credited with the tackle. I'm read pass and started moving towards the LOS just as the ball was being thrown. The full back caught the ball, turned up field and ended up right in my arms. I tried pushing him away but it was too late, the defense caught him and nearly took us both down.
He got up, gave me a look of distgust and started walking away. Being that I'm not a small guy, I simply told him "Sorry but I just can't disappear."
