Even in prefocusing, there is still another problem: The players' 
movements are very quick, hence you select the shortest possible 
shutter speed - something between 1/250 and 1/1000. On the other 
side, you need to open the lens, say to f 1.4 or f 1.0. However,
at these f-stops you need to be "dead on" or at least pretty close
with the distance, otherwise the players vanish into the 'bokeh'  :)
or - more bad - into an USD 2.500 f 1.0 blur :)

If you, on the other hand, have enough light to use f 2.0, then
the 2/50 Summicron should be your nr 1 choice, because (1) the
adjustment of distance is more quick and (2) the lens is more sharp
at f 2.0 . Different, the Noctilux could be nr 1 choice for close-ups 
of any near positioned audience (?, word), coach, players in the cabins 

Just an idea.
