The Cardinals are still looking for a young quarterback. So it made sense, said GM Steve Keim Tuesday, that the Cardinals pick up a couple of quarterbacks for the practice squad. The signings of Aaron Murray and Zac Dysert were officially announced Tuesday morning and Keim talked about bringing both in while on the "Doug and Wolf" show on Arizona Sports 98.7. He said Murray and Dysert were the two highest-rated quarterbacks out there that were practice-squad eligible. It'll be about taking a look at both over the next few weeks and see what they have.

"You can never tell, particularly at that position, until you spend time with them," Keim said.

Keim added that the practice squad, like the bottom of the 53-man roster, will continue to be churned in an effort to find players who can help.

-- As for Matt Barkley, Keim said "I'm not going to say the opportunity wasn't there" for Barkley to return to the Cardinals practice squad. Barkley instead signed to be on the Bears' practice squad. "He probably saw the opportunity in Chicago as a better fit, and we wish him well," Keim said.

-- Why keep nine defensive lineman? If there isn't a great trade opportunity, Keim said, you don't want to give away good players even if there are many at one position. Plus, he added, defensive line is one of those spots where injuries do crop up. Last but not least, Keim mentioned having young players under contract for the future (and it should be kept in mind that both Calais Campbell and Frostee Rucker are unrestricted free agents after the season., so if they left, the Cards still have a nice group of D-linemen.)

-- Keim said there were talks about trading a defensive lineman but the offers the Cards got were not in the Cards' "best interest."
