Now that you've made me go back and read the rule for myself, I'm finding it difficult to find different interpretations for "immediately pulling the ball carrier down". Down, to me, means to the ground....otherwise, we'd have to define 'down' to mean either 'a little bit', 'halfway', or 'mostly' towards the ground. I've been taught not to read any more into the language, therefore, I'll stand by my original statement....with all due respect to Mr. Anderson and staff.
Enjoy your holidays.
