问：2.5对行业格局会产生怎样的影响？ 答：Dean du Plessis could tell Zimbabwean cricket had turned a corner by the noise of the crowd. The veteran broadcaster, who was born blind, has forged a remarkable career as a commentator by distinguishing the game’s almost imperceptible audio shifts. He can tell a slower ball has been bowled by the fractional delay before ball meets bat. He can tell if a batter has pressed forward or back by the scratch of spikes against the hard pitch. And, in 2018, he could tell the sport he loved would never be the same again.
