That's apparently what they want to find out.
According to NFL.com insider Ian Rapoport, the team "will express interest in a possible trade" for San Francisco 49ers QB Alex Smith. However, as Rapoport notes, the Cardinals are "VERY pessimistic" that the 49ers will trade with a division rival.
They have good reason to be, as out of the 25 trades made in 2012, not one was between division rivals.
Smith, who was supplanted by Colin Kaepernick during the 2012 season, has been a rumored trade candidate ever since. A 28-year-old who really came into his own the last two seasons, Smith completed better than 70 percent of his passes for 1,737 yards and 13 touchdowns last season while being intercepted just five times. He had a QB rating of 104.1.
His best game was against the Cardinals in Glendale, when he completed 18-of-19 passes for 232 yards and three touchdowns in a 24-3 Monday night win.
