Tom Brady: Monitors his health with a strict exercise and nutrition plan and regular advanced medical testing.
Ken Stabler: Woke up that morning so figured he was probably ok.
Advantage: Stabler
I'm aging myself but I saw Stabler play as a Raider at Kansas City's Arrowhead stadium. I never saw a more tight spiral. It was like the ball came out of a machine. Perfectly spinning without any wobble.
On a related note, it was also on that day (Fall of 1979) when a Chiefs' mascot called Krazy George (Henderson) had a drum that he banged. Arrowhead is built in sections. He would bang his drum in one section to get people to clap along with him. He would bang in the next section to get that section to clap along with him. He then directed the next section in the same way.
And this is how The Wave was invented.
