Malone had an offensive rating of 89 (beyond putrid) and a defensive rating of 97. So for every 100 possessions he was on the floor the team got outscored by 8. His game score average for the six game series was 7.4 (an average players game score is 10). So by advanced metrics, he was below an average player for that season. Using basic stats he averaged 10 ppg and 8 rpg while having a 20.5% turnover rating (poor).
Duncan scored 21 ppg and pulled 12 rpg. His average game score was 15.4. He had a positive defensive/offensive rating meaning his team outscored the Lakers while he was in the game.
To say that Karl manhandled Duncan is so far from the truth that it makes whoever declares it not credible.
