SB Nation's Dan Kadar and Matthew Fairburn released a joint mock draft on Monday. In it, they have the Cowboys selecting Oklahoma offensive tackle Lane Johnson with the 18th pick:

The Cowboys' offensive line has been in need of improvement for several years and Johnson is the best available offensive tackle. Doug Free just hasn't worked at right tackle and could be pushed inside to help the Cowboys' interior line. The only question about this pick is whether Johnson fits the power blocking scheme Dallas employs. He may need to get bigger, but has the mentality and style to overpower defensive ends.

Another possible need for Dallas is on the defensive line, where Monte Kiffin is switching from a 3-4 to his patented Tampa 2 scheme. They will need extra help along the line to ease the transition, so guys like Jesse Williams and Johnathan Hankins are both possibilities at this spot.
