The way I see it, we certainly didn't get any worse.
Our biggest strengths (Igor, the Powerplay) aren't going to take any major steps backwards, while our biggest weaknesses (center depth, faceoffs, defensive structure from our forward group) SHOULD get a boost.
Blais + Kravtsov should be able to replace Vatrano rather easily.
Carpenter in for Motte is maybe a slight downgrade but he plays the PK just as well and improves an area we suck at which is winning draws.
Trocheck is a very clear upgrade to Strome, no doubt about it.
The key will be if the production from the kids can outweigh the impact Copp had.
The rest of the team is the same, and most of it is young and should presumably take some steps forward. Health will obviously be key and if you can save money for a deadline acquisition or two, we should be in a great spot to improve upon this past season.
