TEMPE, Ariz. (AP) _ The Arizona Cardinals gave cornerback Tom Knight a five-year, $8.22 million contract Wednesday, completing negotiations with all of their draft picks and veteran free agents before training camp.

Knight's package includes a $3.74 million bonus.

The rookie from Iowa, the ninth overall pick in the draft, is viewed as a possible solution to Arizona's problem at right cornerback, a position tested every Sunday because teams usually avoid Aeneas Williams, who plays the left side.

Knight set career records with the Hawkeyes with 10 interceptions for 237 return yards and three touchdowns.

``He's very excited about it,'' agent Kendall Kremer said about Knight. ``I have to compliment (Cardinals vice presidents) Bill Bidwill Jr. and Bob Ferguson. They were very fair, and they're getting things done.''

The last time the Cardinals, who open camp in Flagstaff, Ariz., with a team meeting Thursday night, started two-a-days with everyone suited up was 1988, their first in Arizona.

They came close in 1991, when all of the draft picks signed in advance, but second-year running back Johnny Johnson held out and missed the first two weeks.

Last year, the Cardinals failed to sign a draft pick until the day before camp, and defensive end Simeon Rice and tight end Johnny McWilliams, taken in the first and third rounds, respectively, missed camp entirely.

Rice recovered to record 12 1/2 sacks and be selected NFC defensive rookie of the year, but McWilliams never competed for a starting spot.

``I think it's important for both sides,'' coach Vince Tobin said. ``You've got to be in training camp if you want to have a good rookie year, and if you want to be a good team you need to get your rookies in camp.''

Earlier Wednesday, the Cardinals signed free-agent linebacker Mike Caldwell, a starter last season for the Baltimore Ravens before he was sidelined with a knee injury in the ninth game of the season.

The acquisition was important for Tobin, who waived Seth Joyner last month because of his $3.45 million salary. Joyner signed with Green Bay about the time Caldwell signed with Arizona.

Tobin said Caldwell would back up Jamir Miller at left outside linebacker, Joyner's old spot.

``I think it helps us depth-wise. Without Seth we were concerned about depth,'' Tobin said.

Despite his injury, Caldwell led the Ravens with 4 1/2 sacks, had 76 tackles and returned an interception for a touchdown.

The Cleveland Browns, as the Ravens were known before moving to Baltimore, drafted Caldwell in the third round in 1993 out of Middle Tennessee State.

In his first season as a regular in 1995, he had a career-best 100 tackles and two interceptions.

The signings pushed Arizona's roster to 88 players, three more than they will be able to use in camp. Tobin said he would wait until after physical exams before deciding whom to cut.
