I disagree. The best halves don't have running game as their main threat, but have a good enough running game to make the defence question what they're going to do.
DCE has been the best half in the game for a decade, how's his running game? Reynolds? They can make the occasional break but they're strongest skills are kicking and passing.
Madden has a decent running game, he's not going to score a length of the field try but if he makes a break 20 out he can score.
The problem with AD in the halves is his reluctance to pass the ball. He's a me first player, running or sometimes kicking. And he just doesn't think about creating space and passing to his outside backs. That's why there's still massive question marks on his ability to play 7. He'll get the first month, with Latu out Madden will likely play 14. See how the balance of the team goes
