Since training camp started, there was the possibility -- given the inexperience of right tackle D.J. Humphries, and in total, the inexperience of every tackle on the roster not named Jared Veldheer -- the Cardinals would bring in a veteran tackle to shore the position up. The Cards have already done that at cornerback, although rookie Brandon Williams has been basically unchallenged for a starting role. Mike Jenkins got hurt, and Alan Ball hasn't done anything to change the equation (and Justin Bethel remains on PUP.)

After a first preseason game where both Humphries and Williams had rocky moments, might that change? General Manager Steve Keim said no. And he's got a good reason.

"There's nobody on the waiver wire that has these guys' skillset," Keim said bluntly on the "Doug and Wolf" show on Arizona Sports 98.7. "Unless you can tell me somebody we can find out there, I mean, we're always looking at the waiver wire to try and improve this team and we'll be aggressive and pro-active. But when you take 90 (men on a roster) and times it by 32 (teams), you tell me who's out there, and when you look at who's out there, why are they out there."

Now, that might and very well could change once cuts start coming. But for now, pickings are slim.

On the other hand, Keim reiterated he and Chargers GM Tom Telesco will get together this week when the Cards and Chargers have their joint practices and discuss the two rosters, each team's deficiencies, "in hopes where we can talk about, 'Hey, is there an area where we can help each other improve?' "

Maybe that could mean a trade.
