After going 10-6 and barely missing the playoffs, the Arizona Cardinals are a confident but wary bunch as they open their second training camp under coach Bruce Arians.
Darnell Dockett, who with Larry Fitzgerald, shares the longest tenure with the Cardinals at nine years, says it's his job to make sure players realize that they have to consistently have good practices to expect to succeed in the games.
While the elements are there for a playoff run, several questions remain.
The team's dynamic inside linebackers of a year ago -- Daryl Washington and Karlos Dansby -- are gone. There is competition at right guard, right tackle, tight end and strong safety.
Free safety Tyrann Mathieu probably will miss the first few games of the regular season recovering from knee surgery.
