It is a forgone conclusion rookie Kyler Murray is going to be the Arizona Cardinals starting quarterback. Brett Hundley has played well so far over the first two weeks of preseason and will be his backup.
Hundley has played so well that it looks like he could be a viable backup in Kliff Kingsbury‘s offense. If Murray gets hurt or struggles, there should be no hesitation inserting Hundley.
That said, there has been discussion whether the Cardinals should keep just two quarterbacks on the 53-man roster or add a third. There is no doubt the Cardinals could keep just two with who they have.
