The things described in this article to me points to a leadership issue, not a player issue.
If this many players are disrespecting protocols in droves, then they’re not being led properly.
Don’t blame the players themselves for the lack of attention to detail/discipline. Attitude will always reflect leadership.
Who is telling them to do/not do these things? Are they being told not to do these things or face significant consequences? How is this message being delivered? Are the people delivering the messaging imposing/intimidating enough to get players to fall in line with their message?
These are the things that should be examined, not the individual players.
Remember two years ago when there was a report that came out that "Things seem less rigid now that SP is out of the building," and it was hailed as a good thing? I recall saying that "Rigid sure won us a lot of football games."
But sure, yes, blame the players.
