Going into the second round, Cincinnati's biggest needs are at safety, running back, linebacker, wide receiver and possibly offensive tackle.
The Bengals were one of the best defenses in the league, but safety has been a concern that peaked in 2012 when the team was forced to bring back veteran Chris Crocker. The highly athletic Taylor Mays was unable to secure the starting role for himself and soon saw his reckless play lead to his removal as a starter.
The running game in Cincinnati was decidedly one-dimensional. Free-agent BenJarvus Green-Ellis saw almost 250 more carries than the next-closest running back. That's a major problem, as BJGE isn't dynamic enough to be the team's only back. A strict north-to-south power back, BJGE needs a pacy compliment to help improve the team's run game.
Cincinnati's linebacking corps was absolutely exposed in the AFC Wild Card Game against the Houston Texans. Rey Maualuga in particular has drawn the ire of fans for his sloppy play. Undrafted rookie Vontaze Burfict actually ended up leading the team in tackles despite starting fewer games than the former Trojan.
The Bengals already have lots of young talent that they like (Emmanuel Lamur, Vincent Rey, Brandon Joiner) but none of those players are proven. A strong linebacker could help this defense become absolutely elite.
Wide receiver is still a need for Cincinnati despite its attempts to address it in drafting Marvin Jones and Mohamed Sanu. Neither shined early in the season, but Sanu seemed to show glimpses of brilliance before suffering a season-ending injury.
Neither player caught more than five passes in a game, and neither eclipsed 70 yards in a game. There are holes in both wideouts' games (Sanu,speed; Jones,production), and for a team that has tasted the playoffs twice in two seasons, the coaching staff might not be patient to see how they develop.
The final biggest need is a big maybe. Right tackle Andre Smith has yet to re-sign with Cincinnati after hitting the market at the end of the season. Cincinnati has been willing to let Smith test the market, and while there has been no interest from other teams it appears that the Bengals and Smith are still unable to reach a deal. If Cincinnati isn't confident that they can re-sign Smith, they will have to be thinking offensive tackle in the second round.
