re: Jordan Jefferson (DT) puts up 34 reps on bench at NFL combine

Your weight is irrelevant for bench press, because this is measuring how much you can push with your arms. You’re not lifting your own weight when you shove another player. Having shorter arms is an advantage in the bench, but that will also be an advantage on the field with respect to ability to push off. The disadvantage is not being able to push off far enough to cause your opponent to disengage, but that’s why you evaluate multiple characteristics.
