I'd do one of the extra firsts (not the Sabres own), plus JT's buddy Okposo (50% retained), Larsson, Hunwick, Bailey, and their choice of McCabe/Beaulieu, for W. Nylander, and I'd consider including some way of sending TOR Skinner for the playoffs in a handshake deal for a future trade of low-value pick(s) in order not to include the Sabres other late-round first or a future 1st Rd.
OTOH, Nylander's going to cave at some point. It's a few million over the term of the contract, which he'll spite himself for if he sits out the full year by not signing by 12/1/18.
What is Gardiner going to ask & receive? Is he someone the Sabres should try to pursue in FA as a post-Scandella left D?
