Yes sure but you also named the 3 best teams from the Atlantic last season and Toronto didn't really downgrade in net if anything it's about the same. The leafs had one month of good goaltending and it made Campell look a lot better than he is. Those 3 teams were stacked last year. Florida's Defense will take a hit I think but they should still be a playoff team IMO.
They're also the 3 teams that were ahead of Boston in the Atlantic standings last year, so kind of important. I don't know that I agree on Murray. Over the last 3 seasons he has the 4th worst 5v5 GSAA among all NHL goalies. Only Jones, Holtby & Johansson were worse. He also has the 6th worse 5v5 SV% among goalies with at least 40GP over the last 3 years. All 3 may still be playoff teams, but they also didn't "improve" their teams this off-season.
