Add to that Mike Procter, as well as many others. By all reports, Procter would have been one of the game's greatest allrounders if his career was not cut short after 7 Tests (in which he took 41 wickets at 15).
Consider his first-class record (playing for Gloucestershire, Natal, Western Province, Rhodesia, Orange Free State and South Africa):
21,936 runs at 36.01, HS 254, 48x100
1417 wickets at 19.53, BBI 9/71, 70x5wi, 10x5wm
List A Limited Overs record:
6,624 runs at 27.94, HS 154*, 5x100
344 wickets at 18.76, BB 6/13, 17x4wi
Other notable achievements: scored 6 consecutive FC centuries; hit Ashley Mallet for 5 consecutive sixes, hit Dennis Breakwell for 6 consecutive sixes; hit a 57-minute century; hit a century before lunch then took a hat-trick - twice.
