Yeah, although I acknowledge that is an uncommon take.
His defence was easily the worst of the four (even if this was one of his better years); his postseason passing was the worst of the four; his free throw ineptitude hurt his overall scoring efficiency by comparison to the others; he had the clear best supporting cast; he carried a lot of responsibility for that Trail Blazers series being much, much closer to an upset than it had any right to be; and his volume scoring advantage is overstated because Tim Duncan (who historically outplayed him in their series against each other) was absent in that year’s Spurs series while Hakeem and Kareem respectively faced defensive titans via the 1994 Knicks and 1977 Trail Blazers.
EDIT: I am not sure how you can look at their postseason numbers, adjusted for respective pace, and think Shaq comes across as anything other than the weakest of the bunch.
