The Cardinals won't spend the No. 7 overall pick on the quarterback, but could be doing their homework for the second round or later if Barkley slides. Palmer is 33 years old with 10 years in the league. Stanton, 28, has five seasons of experience.
Barkley, or any rookie quarterback, could have the opportunity to sit and develop for a couple of years in this scenario.
We know Arians loves his quarterbacks. Palmer could certainly steer the ship short-term. Stanton would like the chance to prove himself. But Arians is going to want a young, big-time talent for the long haul.
Barkley has that type of resume, but he could easily slip into the second or third round. Barkley isn't a can't-miss, Day 1 starter, but could have good value with an eye on the future and time to develop. That's a Green Bay Packers type move -- they continuously drafted quarterbacks (Aaron Rodgers, Matt Hasselbeck, Aaron Brooks, Mark Brunell) despite Brett Favre starting.
