An interesting idea might be:
OUT: Kerfoot, Engvall, Holl
IN: Center in the $4.5m range
This would be to give us a strong two-way 3C, get us comfortably under the cap, and free up two wing spots for all of Robertson, Malgin, Holmberg, Steeves, Abruzzese, Knies, McMann, Gaudette, Anderson, Douglas to battle over all year.
To make this work, we probably need to target a player on a team looking to free up longer term capspace by taking on these three expiring deals. So a center making around $4.5m but signed for a few years. Probably looking at it being a veteran from a team looking to rebuild. Not sure how many candidates there are out there but it could work.
