FLAGSTAFF, Ariz. (AP) -- Arizona Cardinals defensive tackle Darnell Dockett rankles opponents with his mouth, is a freewheeling tweeter, even took a shower online.

Quirky? He sure is. Once he steps on the field, though, it's all business, all the time.

Now that his coach and teammates understand Dockett's sometimes-outlandish ways, they've come to accept the eccentricities that go with all the hard work.

Entering his seventh season, Dockett is still going to rub some people the wrong way -- that fight early in camp is proof -- but he has earned respect with his hard work and by playing with injuries.
