This all may be true. Goff obviously has talent. So, let's look at another example for a moment. The WCO was "the" system back in '80's and no one ran it better than Joe Montana. Eventually, he moved on to KC and as old and broken down as he was, he showed he could play outside the 49ers. Steve Young came along and bested Montana's numbers but in his career, he never really proved that he could play at a high level outside of SF. Now, maybe he could have had he had another chance but as it stands, it looks like he benefited from the system more than he was the reason the system was working.
With Goff and McVay, Goff has only played well under McVay while McVay has got production out of all the QB's he's coached. Makes it logical to think that it is Goff who is benefiting more from McVay than the other way around.
Perhaps Goff is unlucky to have so much stacked up in his support but it's a good problem to have. Maybe Goff won't be heralded as a great QB and maybe that's even accurate but if he's the QB when the Rams win it all, I don't think he or the fans will mind.
