With hindsight 20-20 at this point, we can clearly see, thanks to ESPN, that the 2012 class was, well, hardly a contributing factor to this year’s team. Injuries and waivers were the biggest contributing factors to these rookies not seeing any playing time for the team they were drafted by. Maybe if we all chant “20-13″ in unison, good things will happen for us in the upcoming draft! Right? Right??… 20-13! 20-13!…

Anyways, who has been doing their research so far for college seniors and juniors declaring for the draft? Who do you think is a viable and necessary pick up for us? Let us know by leaving a comment below.

Chris Rainey‘s arrest Thursday was the latest issue in what has been a rough rookie season for the Steelers’ 2012 draft class:

First round: David DeCastro, G, Stanford. Severely injured his knee in the third preseason game and returned to play the last three games.

Second round: Mike Adams, OT, Ohio State. Placed on injured reserve with an ankle injury after starting six games.

Third round: Sean Spence, ILB, Miami. Tore multiple ligaments in his left knee in preseason finale and placed on injured reserve before regular season started.

Fourth round: Alameda Ta’amu, NT, Washington. Arrested for drunken driving in October, which led to his release a month later. He was later re-signed.

Fifth round: Chris Rainey, RB, Florida. Arrested for simple battery Thursday. He had 162 total yards and two touchdowns as a rookie. (4:12 p.m. ET update: The Steelers have waived Rainey.)

Seventh round: Toney Clemons, WR, Colorado. Signed off Steelers’ practice squad by the Jaguars in November.

Seventh round: David Paulson, TE, Oregon. Finished with seven catches for 51 yards in 16 games played for Steelers.

Seventh round: Terrence Frederick, CB, Texas A&M. Waived by the Steelers at the end of the preseason and was later signed by the Giants.

Seventh round: Kelvin Beachum, G, SMU. Surprise of the draft class ended season with five straight starts at right tackle.
