The arm talent of these top Qbs is incredible, no play is dead with Allen or Mahomes. They can fit the ball 35 yards down the field with a guy completely in their face with no room to step up. It's remarkable. The margin of error that allows for on offense cannot be schemed against.
Love Tua the person, hoping god I'm hoping he manages to lift through this awful situation he's found himself in. But the arm talent and physicality are not there. Tua's margin for error is significantly smaller so he's going to need to be extremely accurate, extremely fast with his reads, and have the necessary coaching/scheme/players.
The NFL is allowing these big time arms to really thrive, we need one.
