Even though the Dallas Cowboys' fourth and final preseason game is on the horizon, all eyes are on the NFL's Aug. 31 deadline for teams to reduce their rosters from 90 to 53 players.Even though the cut to 53 is always difficult, the Cowboys' depth at meaningful positions will make it an even more painstaking process, as they will likely cut quality players who can make an impact on gameday.With that in mind, let's dive into some bold predictions for the Cowboys' cuts:Keep 6 WRs: Devin Smith,Cedrick Wilson win last 2 spotsWith the first four spots already determined -- Amari Cooper, Michael Gallup, Randall Cobb and Tavon Austin -- the competition for the last receiver spots has been hotly contested throughout training camp and the preseason.Coming into camp, it appeared as though undrafted rookies Jon'Vea Johnson and Jalen Guyton had the inside track, but Guyton's effectiveness has waned while Johnson has continued to have a problem with drops, giving the other receivers on the bubble a great opportunity to move up on the depth chart.Given the Cowboys' depth at multiple positions, there has been speculation as to whether they will keep five or six receivers.
