2014 winning SA u19 side

While I was watching the SA u19 side play Ireland they showed highlights of the 2014 SA side winning the final against Pakistan. Of that SA side only Markram and Rabada made it into the senior side and none of the other names even seemed familiar as provincial players now What the fuck happened to the winning class of 2014 On a positive note young Brevis continues on his run scoring spree making 96 against Ireland following on from his 65 and 104 in his previous 2 matches He looks a talent as does v Heerden the captain who has also batted well making 36, 36 and 111.
