That's why they mortgaged the farm to get him, after all, isn't it?
We should also be guard against keeping expectations too low for a QB that was the first overall pick and costs a bunch of additional premium picks to boot. He's supposed to be capable of more and sooner than your typical prospect.
It really highlights the problem with investing so much in a project like Goff at the most difficult position to play in sports. By the time he's ready to put the team on his shoulders and win games, he's about to be a free agent or already is on some other team's roster. You risk getting all his "learning" years and somebody else getting all the benefit of it.
