Jacques Kallis

Jacques Kallis is the most underrated cricketer ever, with 13,289 Test runs and 292 wickets—numbers that surpass all-rounders like #6 Virat Kohli in combined output. He averaged 55.37 with the bat and 32.65 with the ball, making him 15% more productive than the average top-tier all-rounder. His batting average is 10% higher than #5 Sir Garfield Sobers' Test average, but his all-round contribution remains undervalued.
