Jones is the QB I wanted the Patriots to draft. But my opinion of Jones hasn't improved by much this season since I already had fairly high expectations. I would rank him 8 out 10 which is where I would have put him before seeing him play a snap in the NFL.
He just needs modest improvement from where he is right now to be a very good starter on his rookie contract. If the Patriots had Cam Newton starting this year, the team would have at least one more win. So I don't think Jones has been that responsible for the Patriots success this season but Jones has shown Belichick was right to name Mac Jones the starter. Jones should continue to get better while Cam even if he has a good half season this year with a mediocre team is going to decline with age given he relies so much on his legs.
