When drafting Defensive Lineman, you pick your studs early, then look for some pass-rush specialists to complement them. When drafting Linebackers, you look for consistency in tackles above all, focusing on three-down backers. When drafting Defensive Backs? Anything goes.
Some owners will only take safeties, and pretty much just strong safeties at that, knowing that tackles are more predictable than any other DB stat. Others look for deflections, interceptions and tackles in coverage by focusing on DBs that play alongside a shutdown corner, or rookie corners in general. Still others will go for the gold, taking a return man who might win you a matchup all by himself by taking one to the house.
