For years, the Cowboys lack of overall talent at linebacker has always come back to bite them at some point in a season. Up until the Cowboys spent valuable draft resources on both Jaylon Smith and Leighton Vander Esch, the Cowboys defense went as far as Sean Lee (and his health) was able to take them. Now with one of, if not the best, starting linebacker trios in the NFL, all the attention will be turned to the depth at the linebacker position.
With little concerns about the ability of the big three when healthy, there may be some concerns about who the Cowboys have as their fourth, fifth, and possibly even sixth man at the linebacker position.
