Cardinals quarterback unit analysis

Starter - Sam Bradford. Backups - Mike Glennon, Josh Rosen, Charles Kanoff.

From starter to third string, the Cardinals' main trio of quarterbacks would appear to be as good as any other threesome in the league. It has name recognition and talent. The only real issue, of course, is Bradford's health. He's only played a full 16-game schedule twice in his career and has a very troublesome left knee that could derail his season - and most likely his career - with one hit or dangerous misstep. Rosen seems poised to leapfrog Glennon into the backup role during training camp and the preseason and Arizona will have to make sure he's ready if he's thrust into starting duties. Judging from offseason workouts, that shouldn't be a problem. Many industry insiders believe he should be the starter entering Week 1 regardless.
