What Is The Bengals' Greatest Weakness?

The Bengals have done a great job over the last few seasons when it comes to upgrading different position groups. Where they struggled at the interior offensive line, they drafted Clint Boling and Kevin Zeitler and signed Travelle Wharton. Where they struggled in the secondary, they signed Adam Jones and Terence Newman and drafted Dre Kirkpatrick (though he hasn't seen much action yet). They have made adjustments, primarily in the draft, over the last few years that have made the team stronger.

However, like any other team, the Bengals still have weaknesses. The biggest question is which is their biggest.

At linebacker, the Bengals took a major step forward by promoting Vontaze Burfict to the starting WILL linebacker as he led the team in tackles. They also seemingly upgraded the SAM position by letting Manny Lawson go and signing former Steeler pass rusher James Harrison. However, Rey Maualuga, who was rated by Pro Football Focus as the league's worst 4-3 inside linebacker in 2012, was re-signed and seems to be penciled in as the team's starter for the time being. With his inability to cover running backs and tight ends and his inconsistency as a run stopper, linebacker could be considered a weakness.

Then there's the secondary. The Bengals have Leon Hall and Terence Newman, who both had good seasons in 2012, but Kirkpatrick is fairly unproven and Adam Jones could miss some time due to a possible suspension. The depth at the position after them isn't great. A starting strong safety has yet to be named between Shawn Williams and Taylor Mays. Williams is a rookie, though, and Mays was benched in 2012 after only a couple games as the starter. Some could see the secondary as a weakness.

There's also wide receiver. While A.J. Green has become one of the best wide receivers in the league, there has been no clear standout No. 2 receiver. Many would argue that with both Tyler Eifert and Jermaine Gresham on the field, the Bengals wouldn't really need a No. 2 wide receiver, but until someone consistently steps up and is able to take attention away from Green, the wide receiver position could be considered a weakness.

Maybe it's not any certain player position, but coaching instead. Both Jay Gruden and Mike Zimmer have been applauded for doing great things over the last couple years, but head coach Marvin Lewis has taken some heat even though he has brought the Bengals back from the lost decade of the '90s.

Finally there's quarterback. Many are still unsure of Andy Dalton's ability to lead the Bengals to a Super Bowl, citing his arm strength and the fact that he struggles to move the ball through the air against top-notch defenses. Even for Dalton's supporters, quarterback could be considered a weakness because of the depth at the position. It's unclear if either Josh Johnson or John Skelton could lead the Bengals should Dalton be injured.

What do you think is the Bengals biggest weakness? Is it one of the position groups listed above or a different one?
