martin is 40, which is old enough you would have expected a hc spot by now. not sure that 'up and comer' is appropriate, but i've seen worse resumes. i think i would be all right with him, if he keeps the rest of the staff largely intact (HILL).
hill, well under 30, might be viewed as an up and comer. but i don't think he's quite experienced enough for a top spot in a major conference.
of course, you can now argue that the big 12 is a mid-major conference.....
