The Buccaneers became the first team to sign their 2011 first-round draft choice when they agreed to terms with DE Adrian Clayborn on Wednesday morning.
Clayborn, selected out of Iowa with the 20th pick in the draft, received a four-year deal according to his agent. There is also a club option for a fifth season. ESPN's Adam Schefter is reporting that the deal is fully guaranteed and worth $8.2 million.
The team announced they also signed second-round DE Da'Quan Bowers, LB Mason Foster and TE Daniel Hardy on Wednesday.
Tampa Bay selected defensive linemen in the first two rounds of the draft for the second consecutive season, and the team is expecting Clayborn to make an instant impact with the unit.
On Thursday, the team added TE Luke Stocker, S Ahmad Black and CB Anthony Gaitor to their roster, signing the three draft picks to the team.
