Foster’s an inside linebacker, and the players immediately behind him on most boards are outside backers: Vanderbilt’s Zach Cunningham, Alabama’s Tim Williams, UCLA’s Takkarist McKinley, and Temple’s Haason Reddick. Other than Foster being the first ILB off the board, there’s not much certainty about which linebackers will go when.
