Teams will also be smarter this time around NOT signing guys to longer deals so they have to make accommodations.
Ideally, a team may want to have about 1/3rd of their contracts expiring in any season. This gives the team more flexibility for short, near and long term goals WRT contract distribution.
For instance, on the Sharks for the VGK expansion draft, both Marleau and Thornton had expiring NMC deals; neither had to be protected. As of today, the Sharks have one goalie, two defensemen and three forwards signed beyond 2021; and they are the guys the team would nominally have on the protected list. (There is one pending UFA contract expiring in 2021. All the other guys in the organization are either signed to ELCs that have yet to start or unsigned so will still be exempt, or have contracts expiring in 2019 or 2020 so their future with the organization is undetermined as of today.)
