One thing I will say in Monty's defense - leaning heavily on the top guys is becoming more and more normal in the league. The Bruins' average TOI/G leaders amongst forwards are Pasta and Marchand with 20, Zacha and Coyle with 18 and DeBrusk with 17. Vegas' top 5 it's 17-20 mins per game, Toronto 18-22, Rangers 18-20, Colorado's top 3 play 21-23 then there's a big gap to the rest, Oilers it's 19-21, Kings 17-19, Canes 17-20. And so on and so on.
So the Bruins are doing exactly the same as pretty much all the other contenders, and indeed they're slightly better than a couple of them in sharing the load around. Could they nonetheless be doing more in giving other guys a little more time, opportunity and experience? Yeah I think so, especially in terms of them learning to perform in high pressure and different types of situations. But overall Monty's one of the herd, and in a sense as well he must sometimes fight fire with fire. Pasta and Zacha logged 8 mins in the 3rd period, but Kaprizov played over 9. That's routine for the likes of McDavid and Matthews too. Just the way of things.
