Goodrow isn't actually a bad fit in my (non-Sabres supporting) view. 3C, experienced, annoying to play against. The only downside is he's not worth his contract really but isn't awful.
Not as captain but as a leader.
Dahlin has dibs, if he wants it.
Regardless, Trouba [already a cap, fills need for tuf RD]
and
Goodrow (see above) are fits as plan b, or alternate caps w/character
Trouba - key is if he wants to go there.
Rs will move at 1.5 retained to get 6.5 cap recovered
cost for 2 seasons is a 2nd + a 3rd
Good - we will retain 1.6x down to even 2.0
at that pt he has nominal positive value
something like a 6th + Good for a 3rd or two 4ths, something like dat
