The QB doesn't play in a vacuum. I don't know a QB in the league who could be successful playing in that offense, with the players they have and behind that o line.
Comparing QBs to one in that situation is like putting 2 similarly skilled drivers in an auto race and giving one a Porsche and the other a broken down 1999 Ford mustang and hailing the Porsche driver superior because he won. Well yeah.
Geno is playing in arguably the worst offense in the league and behind the worst line in the league and had turned the ball over 11 times.
Darnold has one of the best o lines in the league, the most electric wr and arguably the most dynamic offense to go along with a top 5 defense and has 10 turnovers.
That's not to say anything about who is 'better' or that Brady was right, but keep things in focus.
It's good to not be the Raiders. It's great to be the Seahawks right now. I think we can all be thankful for that.
