I don't think it will be a big loss at all if Williamson doesn't go, considering you'd think Nicol would get called up, and he's been the highest run scorer and second highest wicket taker this OD season. He has the same problem as Williamson with the bat though, with a S/R this OD season of only 73, which will probably do down in the international game. Our of people who've taken a decent amount of wickets, he's also fourth in best E/Rs. With our injury problems and going by those stats, it's pretty unlikely that he won't be heading over there sometime.
