If Avs re-sign Saad the team is better than last year
Currently the changeover from last year is:
Saad ---> ???
Donskoi ---> Newhook
Calvert ----> O'Connor
Bellemare ---> Maltsev
Graves ----> Byram
Timmins ---> UFA/MacDermid/MacDonald
Grubauer ---> Kuemper
Dubnyk ----> Francouz
In many cases the change is an upgrade. Arguably Newhook can be an upgrade on Donskoi who was a streaky ~40 point forward for the Avs. O'Connor is healthier than Calvert was last year in missing the playoffs again.
Maltsev is a question mark at this stage, hard to tell. Byram is an upgrade on Graves. Kuemper is an upgrade on Grubauer quality wise. Francouz if healthy this year will be an upgrade on the backups we had last year (Miska/Johansson/Dubnyk).
Of course, the big hole unfilled is Saad. Avs will have about enough to pay him $4m or just above, which could be close enough to what other teams are offering to convince him to stay.
So basically, with so many upgrades that are potentially better than last years counterparts the roster could certainly turn out to be better this year than last year.
That's an optimistic view of the situation though admittedly.
