Sports biography plays have generally not had much luck. There was that thing a decade ago I like to refer to as "The Magic Bird" (really "Magic/Bird" but I think my title is much better) that didn't do very well, and it seems to me there was something else right in that same time frame that never caught on either.
Weill and Brecht's "Little Mahagonny" (i.e. the "Mahagonny Songspiel") was originally staged in a boxing ring. It has actually survived the test of time - it's a piece that still gets performed and has a sense of history about it.
