The Sooners looked like they would be world beaters along the front seven before the 2014 season, and even though they sent a second, and third-rounder to the NFL Draft, Oklahoma seemed have a somewhat forgettable group of big men in the trenches. What the Sooners have coming back, is a group of high potential guys that need to figure it out on the field before conference titles become too far removed from recent memory. The Sooners will have far less depth this year, and unlike most years, will likely be crippled by injuries to any starters on the defensive line.
