SA's Guppy according to TT Boy
Northerns definitely the new kings of cricket talent producing in SA. Transvaal/Gauteng, Natal and WP have had their moments. EP/Border have produced top players but couldn't keep them. FS have had their moments especially late 80s-early-90s.
Last 10-15 years coming through domestic system and being strong domestic players pushing for SA honours.
Pretoria Boys : Markram, Harmer, Morris
Affies : Rudolph, de Villiers, du Plessis, Kuhn, K. van Wyk, Wagner ( du Plooy, Kaber, de Swardt, Trumpelmann on the way)
Menlopark : de Bruyn, vd Dussen, Klaasen
Waterkloof : P.Malan, Viljoen [ J. Malan, M. Pretorius on the way]
Centurion : Olivier, von Berg
St Albans : Moonsamy [Former Titans captain Gerald Dros & had recent SA u19 rep Josh van Heerden]
Guys like Dale Steyn, Marchant de Lange, Albie Morkel, Morne Morkel , David Wiese from surrounding areas from the union and from smaller schools. (Mbhalati/Joubert to a lesser extent)
Free State have signed fast bowler Beyers Swanepoel from Northerns school Garsfontein (mainly rugby but cricket is growing like a lot of the schools new to producing cricketers like Menlopark, Waterkloof, Centurion etc) and he opened the bowling with Trumpelmann above and both were unlucky to miss out on SA u19/schools selections.
