49er fan here. Jimmy G is solid. There will be moments he will annoy you for sure, but overall he's very competent. He is excellent over the middle of the field, thats where he is best, and he'll have some weapons to work with there. And for a QB who isnt as good on the outside of the field, Davante Adams is a heck of a safety net. Prior relationship with McDaniels (for years) likely proves beneficial, perhaps most helpful early in season since itll be an abbreviated learning curve of the offense.
