It's actually incredible the job Dubas has done, when you consider he didn't have the benefit of elite players on ELCs like Lou did, and he's still managed to upgrade the team from top to bottom, adding both more elite talent and more depth, making it more skilled, faster, better defensively, and bigger, too.

Last year was tainted by a big dip in goaltending (which will likely correct itself), massive injuries (which will likely correct themselves), and an inexplicable self-immolation by Mad Coach Babcock (which has already been corrected).....but we really shouldn't let that taint the pretty incredible job Dubey has done.
And now we really get to see the benefits when the next wave of ELCs start rolling into the lineup - Robertson, Sandin, Amirov, Liljegren, Hirvonen, Neimola, etc. over the next few years.
