After today's game I'm ready to admit Brady is GOAT. I think Manning's the best regular season QB but Brady is so clutch how can you deny him his honor? The size and speed of today's players plus the salary cap make what he and Manning has done in there careers so impressive. 1. Tom Brady 2. Peyton Manning 3. Joe Montana 4. John Elway 5. Dan Marino 6. Bret Favre 7. Johnny Unitus 8. Rodger Staughbach 9. Steve Young 10. Terry Bradshaw All imho of course.
