Goff is a little out of sync right now. A bit here, a bit there. (And looking good overall despite it.) It's having no preseason starts. Some people speculated that it would make no difference if the Rams starters never saw the field in the preseason. It did, it made a difference, they just don't care--they could use the first games to get in sync.
But that's what we're seeing with Goff. He's not in sync yet. How good will he be when he IS in sync? I think no question better than last year in every aspect of the game, though it's hard to say by how much. It won't be negligible though/.
The problem with speaking up for Goff is that it's the subtle things. Just perfectly placed line drives with eyes, a good pocket sense, that kind of thing. When he's at his best he's an artiste. But it's seldom big wow plays though in the end the effect is the same.
