Madden ALWAYS says holding calls are wrong, he's just against that rule. I'm a fan of Madden, have all his books, gotten every version of the game since I got a computer that could run them, but holding is one of his blind spots. I've watched most of the games he's done color on for at least 15 years and never heard him say a holding call was correct, the closest he ever gets is making no comment, if he comments he says they shouldn't have called it.
I guess you missed the first holding call that Madden agreed with.
