id take either one of them and sink or swim with them for the season.
if they have a good rookie year, you then know theres a chance that they can develop into a decent QB.
if they lose out or win two games, you then have a shot at darnold.
we know now tyrod gives you a 7-9, 9-7 year, and that's against a weak schedule. unfortunately, he is the definition of mediocrity.
gotta get rid of him.
