Observations are either objective, subjective or definitive.
Subjective observation - This one is close to my heart since I played the center position. Center/quarterback ball exchange requires two things from each player for every snap to be successful:
- The quarterback must form both his hands, bottom of palms touching, into a 90 degree V shape, with (usually) the non-throwing hand situated under the crack of the center's butt parallel to the ground.
- The center must hike (e.g. deliver) the ball where the quarterback's hands touch and not into his groin or butt. He is aiming the hand holding the ball slightly behind his butt, not into it.
If the ball hits the quarterback's hands where they meet and the ball drops to the ground, it is the quarterback's fault. If the ball hits the quarterback's fingertips or not at all, it's the center's fault. Tyler Biadasz barely hit Dak Prescott's fingers.
Conclusion: Center caused the fumble.
Objective observation - Virtually every quarterback/receiver connection is made of two components to be successful:
- Quarterback must deliver a catchable pass
- Receiver must catch a catchable ball
Prescott threw a completely catchable pass. Peyton Hendershot caught then juggled the ball and lost control of it.
Conclusion: Receiver caused the interception.
Definitive observation - Defenses' main goals are stopping offensive drives via:
- Downs or
- Turnovers
Quarterbacks must react-and-recognize almost instantly where defenders are positioned near their intended receiver. Any well-positioned defender can undercut a catchable pass.
Prescott's field-of-vision did not account for the Titans' Kevin Byard closely trailing Dalton Shultz quickly enough.
Conclusion: Quarterback directly contributed to the interception, although the defender must also be credited for making a great play.
