How is any of this relevant?
There are two relevant facts: 1) Did James have a concussion? 2) Knowing this, did Leach banish him to a shed where he was forced to stand in darkness?
If either or both of these things did not happen, Leach is being railroaded.
If they are both true, his actions are indefensible.
And for all those people pretending that the standing in a darkened room for 2 or 3 hours (depending upon who's telling the story) isn't punishment, why did Coach Leach cuss the kid out first?
Leach admitted to "locking" the kid up, cussing him out and refused to sign a statement which had such outlandish ideas as allowing a physician to be the determinant of a kid's medical condition.
