If England won all 12 of their remaining matches (3 each against WI away, Pak away, NZ home, and SA home), they'd still end up at only 51.6%! My guess is it'd take not only 12-0 but all the other top contenders Aus, Pak, Ind, and maybe SA to fare really badly, and even then there might have to be a lot of penalty overs for Eng to make it through. Still, that opposition is pretty solid enough for Eng to identify some good players for the next cycle.
