It surely would be easier to admit something that isn't true, but I've been pretty consistent since day one on my take on Jimmy G: physically talented, anticipatory thrower, with no PREDICTABLE weaknesses, such as Kaepernick's long release, which are "fatal" in the sense that a defense can game plan for them.
Here is one of my first posts I dug up making an argument about his strengths and weaknesses, discussing PHYSICAL weaknesses and PREDICTABLE weaknesses:

Of course you cutely responded with "tldr."
I made this post in 2017.
But the discussion was that his weaknesses are not predictable, precisely because his mistakes are mental. The context was with respect to Kaepernick, whose long release telegraphs his throws.
In any event, the reason Garoppolo does this is not really knowable at this point, because he hasn't played enough. Is he just a risk taker? Or is it that he has trouble reading defenses post snap? These things will be revealed later, but no, they do not count with respect to my discussion on "fatal" flaws, because (if it was even me who said that), the discussion was about physical, reliably consistent weaknesses (such as a long release, or lack of mobility, or short height, etc... PHYSICAL problems that can be quantified).
This has more or less been my take on him for some time. He doesn't have any real physical weaknesses. The only weakness he's demonstrated (which I have also commented on numerous times, as I found when I searched through my posts looking for this "no fatal flaw" comment - which I didn't find, mind you ) is that he takes risks he has no business taken.
Unfortunately, there has not been enough film on him to know if he is one of those QBs who will never graduate from third gear to fourth gear and up with respect to reading and reacting to a defense. This remains undetermined, as it was before. Hence why, if I was even the one who made the "no fatal weakness" comment (the only thing I found was in discussion Kaepernick, where I said that not being able to throw with anticipation is one of the most fatal weaknesses a QB can have), it would have been with respect to his physical ability.
