Yeah, here's the thing though, you can't engage in magical thinking when it comes to a rookie quarterback. Look at what the Jets did with darnold, Sanchez and now Wilson. You can't just pretend rookies can magically run the full offense right away.
I very much doubt that Jones is going to grade out with Alex Smith as his ceiling. But what they're doing is adding a few new wrinkles each practice, making sure they're built on solid fundamentals, and not putting the kid through more than they've worked him on yet.
If you really think this is the best Jones is going to be able to be we shouldn't have taken him in the first round. What he is, is the best he's going to be able to be literally 2 games into his professional career. This is about as limited as we'll ever seem them play Jones, because they're going to bring him along in accordance with a well devised plan. This is the cases regardless of what fans or Jones himself thinks about it. They're not going to ask more of Jones than they know he can deliver.
He'll get chances to prove his growth as the year goes on and the reins will slowly loosen, but they're not going to pretend their rookie is a 5 year veteran the way the Jets do. And I think history will quickly prove that Belichick's way of doing things is much better.
