You bring up a good point, Roy.
I'll add that if the coaching staff knew of the injury before that last play, he shouldn't have been in the game.
And regardless of his injury status at that point, I think the ball should've been only in White's or Brogdon's possession, with Grant, Muscala, and Hauser limited to catch-and-shoot. Grant isn't a shot creator, so he shouldn't be putting the ball on the floor and trying to make a move, especially with the game on the line.
