The Bears will almost certainly look to upgrade their defensive line after they were dismantled by opposing running backs and struggled to generate much pass rush in 2013.
The Bengals aren't in the market for a top-tier quarterback, but with Andy Dalton coming off another disappointing postseason showing, Cincinnati might target a mid-round developmental prospect such as Georgia's Aaron Murray.
David Wilson's neck surgery leaves the Giants thin at RB, but they can get help there later in the draft. Their early picks should go to the offensive and defensive lines, as well as the CB rotation.
Outside of Romo, Murray, Bryant, Witten and Tyron Smith, pretty much all parts of the Dallas roster could use help. The lines are in the worst shape, though.
