Given the totality of DA’s record as an NFL coach, it’s extremely speculative to assume he would have produced a 10 win season if the team just had a normal level of injuries.
DA started losing the locker room his first year. He made bad in-game and roster management decisions every year, and his teams lost multiple winnable games in which injuries were tangential at best.
I am not trying to dog-pile on the recently fired, but his teams never beat good teams, lost more than they won against average team, and lost too many games to bad team.
Given that, it seems intellectually obtuse to declare that if the Saints had been injury free (which doesn’t exist in the NFL) his team would have won 10 games.
I mean, sure, it’s possible, like getting struck by lightning, but not close to probable, based on a lot of evidence.
