It comes as no surprise that the Cleveland Browns have the largest rookie pool. With 11 draft picks, including two first-rounders, the Browns were allowed to spend $9.7 million to sign their selections.
The league determines the numbers for the rookie pool by how many picks a team has and where those picks were located in each round.
The Ravens were the first team in the NFL to sign all of their draft picks. There's only two unsigned picks for the Steelers (guard David DeCastro and linebacker Sean Spence) and the Browns (running back Trent Richardson and quarterback Brandon Weeden).
The Bengals still need to sign six of their draft picks: cornerback Dre Kirkpatrick, guard Kevin Zeitler, wide receiver Mohamed Sanu, defensive tackle Brandon Thompson, tight end Orson Charles and running back Dan Herron.
