lunch-pail mentality
n.— «He has what I call a lunch-pail mentality.…Tommy comes to work every day, and outworked people in practice. He called all our signals in the secondary, and was our quarterback on defense. Tommy is not only a good football player, but a wonderful young man. He is the consummate student-athlete, with a grade-point average above 4.0.» —“Irvin is Vikings’ defensive quarterback” by Cliff Mehrtens Charlotte Observer (North Carolina) Dec. 25, 2006.
