Yes he is probably better as a passer than what we saw from Cam. That’s not a high bar to step over.
I’ve never seen a Stidham game and said “wow this kid has IT” like I did with JG. Can’t read pressure pre-snap, panics when he sees an NFL level pass rush, doesn’t make good decisions, can’t see the field as you said, not impressed with his movement in the pocket and his mobility is not at all as advertised. The problem is he’s also approaching 25 years old. A 25 year old QB prospect is not a prospect anymore IMO. If he hasn’t shown improvement by now, and he hasn’t, I wouldn’t count on it ever happening. That’s not unusual for a 4th round draft pick QB. There are plenty just like him.
He isn’t starting for this or any NFL team so I don’t see what the Patriots have to gain by benching Cam now.
