Incidental contact ?

[Kelvin green]

how many players really fall down by themselves?

If the player fell down by the actions of another player, I look at a foul.

If the player truly fell doen by themselves then no foul...i

ncidental contact...

Similarly, contact which does not hinder the opponent from
participating in normal defensive or offensive movements should be considered
incidental.

Sounds like the play described the player was hindered in normal offensive movements... Foul!
