FLAGSTAFF, Ariz. (AP) -- The Arizona Cardinals' defense is well aware of its status as the anointed strength of the franchise.
The players have a bit of swagger to them this training camp, a confidence mixed with the reality that they have done nothing yet, that all the success of the second half of last year means little if it can't be repeated or improved upon in the coming season.
Coach Ken Whisenhunt says "confidence doesn't mean a thing unless you produce."
He says he judges the situation more by what he sees in practice, and that's a defensive unit that works hard and is trying to build on what it achieved last year, when Arizona won seven of its last nine games.
