Just days later, Arians employed that hook.
Originally, Arians was set to start rookie Thomas, assuming he appeared in command and ready in practice. Thomas did not, per Rapoport.
When naming Thomas the starter this week, Arians said it was more about finding out what the rookie could do than passing judgment on Lindley. It only took Arians a couple shaky practices from Thomas to know he couldn't ride the strong-armed rookie in the finale.
Lindley completed just 41 percent of his passes en route to six points in the loss to the Seahawks last week and has zero touchdown passes in his 225 career pass attempts. Still, he's better prepared for the aggressive 49ers defense than the fourth-round pick, Thomas, who has always been viewed as a long-term project.
