Things are different with his new team. The Arizona Cardinals released former starter Kevin Kolb last week. They signed Drew Stanton, who served as Luck's backup last season and hasn't thrown a regular-season pass since 2010.
Despite that, Arians appears high on the five-year veteran. During an appearance on "NFL Total Access" from the NFL Annual Meeting on Monday, NFL Network's Andrew Siciliano asked the coach if the Cardinals currently have a starting quarterback on their roster.
"Yeah, we got a very capable one in Drew Stanton we just happened to steal away from (Colts coach) Chuck (Pagano)," he said. "Drew knows the offense, he's more than capable of doing it and if he's our guy, I'm comfortable."
NFL.com's Ian Rapoport reported last week that the Cardinals are unlikely to draft a quarterback in the first round and are content for Stanton and Brian Hoyer to battle for the starting job in training camp.
Arians apparently views Stanton as an untapped talent in need of an opportunity. It seems awfully risky to us, especially considering the fever dream of musical chairs the Cardinals suffered through in 2012.
