In the case of Brady v. NYG d line, Brady had avg to poor performance as NYG d line had outstanding performance. Brady could not overcome this.
As for yesterday's survivors I see Cincy w/excellent dee and outstanding QB play.
SF had avg QB play and an outstanding dee performance.
BUT...
I remember the SF-KC SB and the SF dee was outstanding, especially for 3 to 3 and a half quarters.
I thought the JG missed TD pass was a huge contributor to the outcome.
On the contrary, I saw Mahommes sheer elite individual talent will his team to victory over an otherwise dominant defense.
An elite QB/offense "usually" loses to a dominant defense.
But there are those occasions where the top dog QB puts the team on his back and shines in the face of adversity.
Soo...the age old question continues. Can an elite QB defeat a dominant defense?
I guess we'll see how it all pans out this year for sure.
