It’s interesting that you bring up the good ole boys vs the new kids.
Both have there flaws, but like anything in life balance usually is the best course.
While I do think analytics will overtake the dated guy check approach of the older guys, the data and metrics are not quite there yet. But, since the NHL has moved to player/puck sensors and clubs have built analytics departments, it’s only a matter of time.
I still think there will be value in GMs though. You still need a vision from which to deploy analysis, you still need master negotiators and you still need people who can assess a players character and mental makeup.
