I'm quoting this ^^^^ just to get it out there again. saintsfan1972 is spot on. Y'all worrying about whether he goes to the PS can settle down. It isn't an issue as the rule change mentioned above now exists.
He sticks as the 3rd QB on the main squad under that new rule.
My 10,000ft view is that he simply came out like a deer in headlights but got over that after the int. He played pretty good down the stretch.
Some of his problems early directly related to him being more advanced in the gamebook than his receivers. A lot of mistakes out there by a lot of people.
I can't yet know how good or bad he's going to be. Will probably not know this year as he isn't going to get a chance to see how he can play with the starters.
But I think he'll be fine. He did show, imo:
A quick release
Ability to go through progressions quickly (which helps the quick release - see Brees)
No cannon, but an above average arm
Just enough mobility to elude the rush and step up into the pocket (something most rookie pocket passers have trouble with at first)
