There aren't 32 better qiys regardless of if they're starters . That's fact

Kaep is listed as the 29th QB last year according to ESPN stats, and that's probably generous. He's a college type QB ( Tebow) who success was based on playing the QB position like a RB, worked for a bit but not what you really want out of QB.
Let the Falcons sign him as a backup and then see if he can run that offense like Ryan, should Ryan get hurt.
