Jacques Kallis

Kallis is the statistical case for the greatest all-rounder: over 13,000 Test runs, 45 hundreds and 292 wickets, plus over 11,000 one-day runs and 273 wickets. He batted in the top four and bowled genuinely fast-medium, often as South Africa's fourth seamer. The workload is the point: he did both for nearly two decades in Tests and one-day cricket.
