Debate: Alex Smith trade fallout
The Cardinalswere interested in Smith, but now they're moving on to option No. 2. Arians wants to push the ball downfield and even though Cassel isn't known for his cannon, he would be an upgrade. Cassel did throw 21 touchdowns and 11 interceptions in 2008, and 27 touchdowns and seven interceptions in 2010. So there's proof of success, just not sustained consistency.
Cassel isn't the long-term franchise quarterback, but he should be capable of leading a playoff run on a team with a strong defense and Larry Fitzgerald catching balls in this what-if scenario. Kolb and Cassel are two of the most recent precautionary tales in terms of signing free-agent quarterbacks with minimal experience, but at least Cassel kept the starting job in Kansas City and led the Chiefs to the playoffs.
