The problem here is that you have made a blanket statement yourself (by claiming that analysts make that blanket statement), and also rely upon a truism (the playoffs are "different" in a meaningful way). What you're probably missing is the amount of analysis that has gone into a question like that, which reveals the strong effect that variance has on the playoffs.

If there are real differences in these players, it should be persistent and repeatable. And yet, clutch players one year often disappear the next, and "playoff" teams fail to repeat their performance.

Luck is never the only factor. But it's a biggie, the fewer games you play. That some teams perform differently in the playoffs being used as evidence that the playoffs are different is circular reasoning, and normal variance explains it just as well without begging the question.
