This Dobson rumour is worrying. How much of a benefit would he be if Hronek and/or Myers are shoved down the depth chart? Neither have been bad this season, when not anchored by a certain someone.
Pageau, Nelson, Barzal....or Horvat....would all be better targets.
But if we're talking replacement centers, Seattle seems to have a bunch of them. Gourde is injured and UFA, so I feel could likely be had for a song. McCann and Stephenson are more who I'd be looking at, but wouldn't be as rentals, given what I imagine their cost to be.
