Outside the 17 & 18 season with the rams , Dak has played with much better talent and supporting cast. Goff was pretty much going to written off as just another average QB until rewriting his career.
Outside of fantasy football stats(Dak is my fantasy QB for a reason) Goffs post season playoff teams have been more successful.
Hundreds of things go into stats every particular year that determine the outcome. Talking stats at face value is dumb.
Dak has much greater regular season success. Goff has better post season success
If you want to talk stastics. Cousins is damn near identical to Dak statistically and no one thinks hes better the Dak.
Don't think either QB has what it takes to win a superbowl but "statically" speaking Goff posts better post season success.
