Zac Dysert wasn't out of work long. He was cut by the Cardinals Friday and then claimed off waivers by the Cowboys, it was announced by the league today. Dysert didn't last as long as the previous third QB, Matt Barkley, in terms of seeing what he had. Barkley at least made it through training camp.

But circumstances change. One, it means that Trevor Knight, the undrafted rookie out of Texas A&M, has shown enough in this short time to impress -- at least impress enough to keep him over Dysert. It also means the Cards -- not surprisingly, given the praise coach Bruce Arians has delivered anytime he is asked -- are happy with Blaine Gabbert thus far. Third, it means that they are good with Carson Palmer having his normal workload in training camp, even with an extra week of camp and extra preseason game.

There is context needed everywhere. I don't expect Palmer to get a lot more preseason work, so with an extra game, there should be more preseason game reps for Gabbert, Knight and Drew Stanton. As for Stanton -- and Gabbert -- last week Arians said clearly that Stanton remains the No. 2 QB. I don't expect that to change this season, but camp can always make an impact. (It won't, IMO.) Still, QB is always a sexy position, and there will be plenty of stories of all four guys once camp starts in mid-July.
