His argument was more centered around TO's as Golson also put up really good numbers in some of the games he had the most TO's. Also, I think that breakdown of opponents is a little misleading as just because they are his best opponents doesn't mean that they are good opponents in fact SMU was 1-11, Miami had a losing record, etc. I believe he broke it down into Power 5 games and he threw 5 INT's and 8 TD's against OSU, VT, and Miami. He also included fumbles as well but I'm not going to spend the time to find those. ECU for example huge game throwing the ball but also had 3 INT's so can he sling it, for sure. But he also turned the ball over a fair amount against good competition. Lastly, look at their losses, he had 9 Td's and 6 INT's in the 4 games they lost (OSU, Memphis, Miami, VT).
Also, let me add that using QB rating as a gauge of success I've read can be very misleading for example Golson versus ASU had a QB rating of 141.6.
