Avs do not necessarily have to trade Stastny for prospects/picks though. I could see several situations where they trade him to a team for a #2 or #3 D man and a third line player.
If it does come down to wanting a bigger role and cash for Stastny, Buffalo makes a ton of sense to trade with for the Avs.
Myers or Ehrhoff would be huge adds for the Avs for Stastny. Maybe get the Sabres to throw in someone like Steve Ott for the playoff push.
Avs Get:
Myers (would be my choice for the long term upside)
Ott
Sabres Get:
Stastny
Elliott
Hishon
Conditional 1st 2015 if Stastny does not re-sign
O'Reilly-Duchene-Downie
Lando-Mac-PAP
McGinn-Mitchell/Ott-Tanguay
McLeod-Ott/Mitchell-Bords
Hejda-Johnson
Benoit-Myers
Wilson-Guenin
Working Barrie and Malone as the depth players.
For the playoffs you probably look to add a 3rd or 4th line center at the deadline to allow thug buddy Bords to sit and run a 4th line of McLeod-Mitchell-Ott if you get the right 3rd line player.
Swap PAP to play with Mac for the speed factor. Tanguay plays on the 3rd line which is asked soak some of the shutdown time. In certain situations, i.e. a close playoff game where the Avs are looking to hold a lead rather than score a goal, you can shift O'Reilly down to the 3rd line for face-offs and pop Tanguay or McGinn up to the 1st line, though I would try to keep the 1st line intact as much as possible.
Myers IMO suffers a bit from the same thing that EJ does/did, trying to live up to unrealistic expectations. Put him on a 2nd pair with Benoit, who seems to be a steadying unspectacular force on the ice, and let him relax. Wilson and Guenin make a solid 3rd unit.
In the offseason the Avs have options. Trade Barrie for a better long term option as the 3rd line center. Re-Sign Ott or Mitchell if they can take the role on over a 2-3 year span. See if Malone develops into the player he can be. Sign a UFA...
All that said, it sucks that Paul is not signed for one more season past this..... I would much rather be facing the choice of keeping him or letting him go after seeing a full season and a half of Mac. He has some growing to do still and I do fear breaking him if you push too hard early.
