No stone unturned would undersell the level of detail teams uncover on prospects in the year leading up to their draft eligibility.
NFL front offices use their scouting staffs and security details to become prospect investigators during the evaluation process.
As one general manager put it, "We know about your first girlfriend and your last girlfriend, if you were a good teammate, love the game and what you eat for breakfast."
Interviews at the Senior Bowl, Scouting Combine and other campus visits or phone calls with teams serve as tools to compile a complete profile of every player on the draft board for all 32 clubs.
