Easy for Stanford is still harder than most schools.
Also, if they didn't do this they would be doing their student-athletes a disservice. Student-athletes contribute much more of their time to a university than the typical student. When filling corps class requirements, I would hope academic advisors would steer them into courses that would take less of their time.
I hope (and am pretty sure) they are doing this informally at ND (i.e., advisors let them know which courses require more effort/time).
