re: The moment I was sold on Burrow. Brennan will get there as well.

Burrow and Brennan are completely different in their mental toughness and makeup. Perhaps Brennan will improve in his decision making and maybe the game slows down for him. We have to hope so because O and Ensminger have no real alternative.
Burrow held the onto the ball too long in those earlier ‘18 games because his receivers weren’t open. Brennan held onto too long because he was tentative his decision making was slow.
