This is a congruent conflation of “over the hump” and “monkey off (one’s) back”, both meaning to get over a persistent problem.  The speaker may have been thinking of a “hump back”, or perhaps a “hunchback”, but I don’t recall Coach Reid with one.  When I received this malaphor, I immediately thought of Igor (Marty Feldman) from the movie Young Frankenstein who deliberately swapped which side the hump on his back was located, saying, “What hump?”  A big thanks to Jim Kozlowski, loyal Eagles fan, for spotting this gem.
