to expand on that, according to legend more or less, back in 09 at Worlds, there was no Mando, and everyone just threw for the basket, probably not in the same fashion as Nikko, but in that direction. Because of that, they have added a mando, but it clearly is not forcing players to play it as intended.
This is something that I bet a lot of guys have been eyeing in practice, as Feldberg was 2 cards ahead and was playing 11 after Nikko had thrown and said he told Jeremy Koling to try the same thing.
One other point of interest, it seems that the whole reason Nikko went for it was based on the result of McBeth's shot on the card ahead. McBeth had made a similar, probably better shot than Nikko and Nikko went down while McBeth was getting ready to throw to see his lie. There was also a delay while 11 was playing through before Nikko's shot, so all told, Nikko had the tee for about 7 minutes before he threw. Brinster made a comment about this but not much else was said.
