The Saints added some competition for second-year CB Johnny Patrick to beat out for the nickel CB spot by signing CBs Elbert Mack and Marquies Johnson along with drafting CB Corey White. Yet Patrick continues to display why he's the frontrunner for the job during Wednesday morning's minicamp practice. He made a leaping, full extension interception off QB Chase Daniel that was arguably the top play of practice. Patrick was with the first-team nickel defense on the play.
