The 6.5 280lb Ealy isn't falling out of the 1st round. With his prototypical size in high demand, he could be off the board before our choice @ 16.

Cowboys try to find a piece in the first round that will immediately come in and provide a pass rush for a front seven in desperate need of play makers. At this point, Kony Ealy is the best man for the job.
At 6'4", 273 pounds, the Missouri Tiger standout has the athletic ability to contribute immediately to what appears to be a rather weak defensive line. Ealy spent time all over the defensive line and at outside linebacker at Missouri, proving his versatility. I believe that Rod Marinelli will be able to get the best out of Ealy, and that could end up being very scary for Cowboy opponents in the future. The 22 year old has excellent agility and all of the tools necessary to develop into a double digit sack guy.
While one can argue that defensive tackle or outside linebacker are just as great of a need for the Cowboys, the talent gap between the 2nd round guys at these positions and those currently available are not as great as the gap between Ealy and the guys available at DE in the 2nd round.
There is no question that Ealy is the 2nd best DE in this draft, behind only Jadaveon Clowney. Kony Ealy is a nice fit for what should be a draft filled with defensive prospects for the Cowboys.
