Two years ago there was a situation with two key players for NW who were suspended for the opening Sectional game vs Northridge due to an incident. This incident happened the day before the game, but was brought to the staff the day of the game. So to answer your question, yes, I’m sure NW would’ve acted in similar fashion.
As for the Northridge incident, it was ultimately the school’s choice to suspend the kids for a game I believe. If it happened off school property and during the summer, couldn’t they let it slide? Every situation is unique, but sooner or later there has to be a timeframe where “the past is the past”. It may be subjective and not clear-cut, I understand that.
The caption and picture seem obvious, but how is someone going to prove he was high? There would need to be a video showing the action of smoking IMO or do a drug test.
