I'm not buying into the "doesn't have an arm" narrative. Max has a very short, compact and quick delivery, which IMO is huge for the NFL. Many of his throws were completely flat-footed - he didn't even move his front foot. That's all arm strength.
That quick release is IMO a big deal in the NFL when you have secondary players who, when the QB starts a windup, will jump the route and make the interception. When QBs put a lot of heat behind a throw there's a wind-up and they take a step into the throw, meaning a much longer release (e.g., what AK did on every single throw every time).
For the NFL I'll take a quick, compact release every day over someone who can throw the ball five yards longer than another guy. The former is used on basically every throwing play, the latter on just a last-minute hail mary.
