The Dallas Cowboys came within one win of a postseason berth this season, but a Week 17 loss to the Washington Redskins locked them into the 18th overall pick in the 2013 NFL Draft.

Dallas, after firing defensive coordinator Rob Ryan and replacing him with Monte Kiffin already this offseason, will be looking to revamp their defense, which struggled with both injuries and ineffectiveness at certain points during the regular season.

According to SB Nation's Dan Kadar, in his most recent mock draft on Jan. 14, the hiring of Kiffin could certainly affect their first round selection process. He sees the Cowboys taking Sharrif Floyd, a junior defensive tackle from the Florida Gators, with the 18th pick in the first round.

Here's Kadar, on the choice:

It's true, the Cowboys desperately need offensive line help. While most fans want needs to be filled, NFL teams often weigh a combination of best player available and need. With Monte Kiffin taking over the defense, the Cowboys may switch to a four-man front. If they do, they'll need help at tackle. Floyd is the kind of lineman who can play outside in power three-man fronts or tackle in a four-man set. He may need to play inside after nose tackle Jay Ratliff played in just six games this season and Josh Brent's playing future looking bleak.

Floyd is the sixth overall prospect at his position, according to CBSSports.com, and the 39th-ranked prospect in the entire draft pool.
