Keller
Galchenyuk
Schmaltz
Chychrun
Dvorak
Stepan
Grabner
Raanta
We have pieces.
Looking at those pieces:
Keller - ranks 43rd among C's. Compared against RW's he ranks 20th. So an ok 1st liner, good second liner
Galchenyuk - 3rd line/2nd line tweener. Not certain he can be a C.
Schmaltz - not enough data but similar to Keller. So an ok 1st liner, good second liner
Chychrun - A good #3 D
Dvorak - a good #3 C with 2nd C upside
Stepan - 3rd line/2nd line tweener
Grabner - good 3rd liner/great 4th liner
Raanta - top backup in the league. Jury out if he can be a starter.
Adding OEL - a #1 D and Hayton - projected 2nd line C.
I also like Crouse and Fischer but they are 4th liners with 3rd line upside (offense is a huge weakness)
We NEED several high quality pieces. Still need at least 2 top 6 forwards, ideally a first line C, first line LW and a 2nd line RW. Add those and the team has depth. Galchenyuk, Dvorak and Stepan can all play UP a line if/when injuries occur. Really need a better partner for OEL on the RHS.
xx - xx - Keller
Galchenyuk - Schmaltz - xx
Dvorak - Stepan/Hayton - Grabner
Crouse - Richardson - Fischer
OEL - xx
Chychrun - Hjalmarrsson
Goligoski - Lybushkin
Those holes will take years to fill via drafting and developing. Chayka has to look at UFA market and hope to strike some gold.
