Yea-up. It's part of what makes a QB more effective. It also, like a good point guard, gets and keeps more players involved in the game. That not only makes it harder on the defense to key on one or 2 guys, it makes the offense run smoother because everyone has an active role.
It IS what makes Brady more effective, and Drew is getting the same benefits. Nice to hear some others taking notice too, when Al Michaels and John Madden noted it last night.
