Herm Edwards, Tedy Bruschi and Bill Polian agree Tom Coughlin is doing everything in his power to turn the Jaguars into a winner with the addition of CB A.J. Bouye. (0:49)

Former Texans cornerback A.J. Bouye has agreed to a five-year deal worth $67.5 million -- including $26 million fully guaranteed -- with the Jaguars, a source said. The deal works out to $13.5 million per year.

The Jaguars also agreed to terms with Arizona defensive end Calais Campbell and Dallas safety Barry Church on contracts totaling more than $150 million, according to a person familiar with the deals. The person spoke to The Associated Press on the condition of anonymity because the Jaguars won't announce any moves until players formally sign Friday.

The trio should significantly improve a defense that ranked sixth in the NFL in 2016 but failed to generate game-changing turnovers.

Retired NFL receiver Steve Smith tweeted his approval of the Jaguars' moves.

Bouye was one of the best cornerbacks available this offseason. He replaces Prince Amukamara and will play opposite budding star Jalen Ramsey. Together, they should make the Jaguars considerably tougher to throw against.

The Texans chose not to use the franchise tag on Bouye, as the price tag of $14.21 million was prohibitive.

The former undrafted free agent entered last season as the Texans' No. 4 cornerback, but because of injuries and his impressive play, he became their best defensive back by the end of the season.

Bouye had 63 tackles, 1 sack, 1 interception and 16 passes deflected during the regular season and an interception in each of the Texans' two playoff games.

Church agreed to a four-year contract worth $26 million, the source said.

The 29-year-old Church will replace Johnathan Cyprien, a second-round draft pick in 2013. Cyprien had more than 100 tackles in each of the past three seasons, but he rarely made big plays. Cyprien has two interceptions and four forced fumbles in 60 games. Church has 488 tackles, seven forced fumbles and five interceptions in seven seasons with the Cowboys. He missed four games last year because of a broken forearm.

The Jaguars also agreed to terms with Buffalo linebacker Lerentee McCray on a one-year deal worth up to $3.5 million, the person said. The deal includes $1 million guaranteed. McCray, who was born and raised in nearby Ocala, is expected to play a backup role behind Paul Posluszny, Telvin Smith and Myles Jack in 2017 while serving as a key member on special teams.

As much praise as the Jaguars got for landing three of the top defenders available Thursday, the moves raised questions about a lackluster offense. Jacksonville's failure to find any consistency on that side of the ball last season was the main reason for the team's 3-13 record and the dismissal of coach Gus Bradley.

The biggest moves top executive Tom Coughlin, general manager Dave Caldwell and coach Doug Marrone have made so far on offense are trading for Miami left tackle Branden Albert and parting ways with tight end Julius Thomas.

Those trades were formally announced Thursday.
