There is really no need to sign any UFA vets. At this point next year, White, Chabot, Duclair, C Brown should all fit the "vet" criteria, while be much younger than your standard "vet". Unfortunately, there will be no room for coaches selections like Ennis, Sabs, etc.
Brown, Batherson, Norris, Formenton, Balcers, Abramov will all be pushing for roster spots next year, they are even proving right now that they are very close. The team should definitely re-sign Connor Brown, Duclair and Nick Paul. Add in Tkachuk, White, and the already under contract Anisimov and the forward position is pretty stacked and that's not including Pageau, who they may want to extend, nor would there be room for both Byfield and Lafreniere once we draft them 1 and 2..
