FILE - In this Sept. 16, 2017, file photo, Notre Dame's Robert Hainsey (72) and Khalid Kareem (53) celebrate with teammates after defeating Boston College 49-20 in an NCAA college football game in Boston. Notre Dame junior Khalid Kareem found himself lost in the defensive line shuffle for most of his first two seasons with the Irish. Always buried on the depth chart, the Detroit native just wanted a chance to prove that he could become a regular contributor, and perhaps even a starter. A late-season surge in 2017 followed by a stellar showing in spring ball earned Kareem his chance at both.(AP Photo/Michael Dwyer, File)
