To no one's surprise, the Arizona Cardinals traded quarterback Josh Rosen on Friday, sending him to the Miami Dolphins for the 62nd overall pick in the second round of the NFL Draft.

Once it became general knowledge that the Cardinals would be taking University of Oklahoma signal-caller Kyler Murray with the No. 1 overall selection, it was obvious that the writing was on the wall for Rosen's departure, even though Arizona took Rosen in the first round a year ago.

The thing is, the Cardinals traded up just to take Rosen at No. 10 last spring, so giving up on him after just one season and essentially losing out on a bunch of picks in the process has rubbed a lot of people the wrong way.

But Cards general manager Steve Keim is defending his team's decision to make the trade, saying it was a chance Arizona had to take:

“It was really about the opportunity,” Keim said, according to Cameron Wolfe and Josh Weinfuss of ESPN.com. “Certainly, all of us are big fans of Josh Rosen's, wish him well and think he's going to have a heck of a career in the NFL.”

Rosen had a very disappointing rookie campaign, starting 12 games and throwing for 2,278 yards, 11 touchdowns and 14 interceptions while completing just 55.2 percent of his passes and posting a passer rating of 66.7.

However, Keim refused to say that the quarterback did not work out with the Cardinals:

“I don't know that it wasn't that he didn't work out,” he said. “I would say, obviously, he was put in a tough situation last year. But I think, really, when you come down to the bottom line, is we had an opportunity to find a dynamic player that we think can be special.”
