Retiring numbers

If I'm not mistaken, Doak Walker's #37 is the only retired number at SMU. But from what I hear, there is some discussion within the inner circles of the athletic department about starting a wall (or something) within Ford Stadium of retired numbers. Clearly this should remain a VERY exclusive group. Who would you think should be honored?
My nominees:
Doak Walker, of course.
Forrest Gregg
Eric Dickerson
Raymond Berry
