Here is a video by NBA earlier this year "What the NBA Referees use to determine a hard foul, Flagrant 1 or Flagrant 2."
Very interesting to watch this side by side with Lin's flagrant foul video.
I can't believe NBA would concluded after review,
While some of the plays in the video involved hard contact, none was subsequently deemed a Flagrant Foul given the full circumstances, angles and comparables from past games.
So basically NBA determined that clothline and upper cut move are not excessive and necessary.
