I think that there is healthy enough to play, which is determined buy the medical staff
There is healthy enough to be willing to play, which is determined by the player
And then there is healthy enough to play well, which is determined by the Head Coach

The medical staff felt Baker could play without significantly increased risk of injury.
That played out to be true.

Baker felt healthy enough that he was willing and wanting to play.
This certainly demonstrated his toughness.

KS felt Baker was healthy enough to play well.
That was certainly not the case
KS was wrong and that is why he is getting criticism, which I think is appropriate.

The people not get enough criticism is the Front Office.
Baker was playing at 50, 60, or maybe 70%
If Case Keenum is not good enough to give him a couple games off to heal up some then why were we paying him $10 million last year?
