The Atlanta Falcons wanted to be a test case for a different way of handling the quarterback position, if only because their bungled pursuit of Deshaun Watson cost them that quarterback option and the best passer in franchise history after they shipped Matt Ryan out in the aftermath. Atlanta would find a player they liked in the draft without sinking in a top ten pick, sign savvy veterans to bridge and serve as fallback options, and build up an offense filled with playmakers so that player could succeed.
I don’t think the Falcons expected that experiment to generate elite quarterback play, but I think in their hubris and hope they believed they would not need it.
