Critiquing plus/minus and corsi fairly

There is a recently posted article on BroadStreetHockey.com discussing overused and overrated statistics. The first statistic on that list is Plus/Minus. Plus/minus has its flaws and gets wildly misused at times but it doesn’t mean it is a useless statistics if used correctly so I want to defend it a little but also put it in the same context as corsi.
