So you're left with the reality of having to play Tanguay or PAP on the 3rd line again. Avs desperately need a defenseman. One guy has trade value, one guy doesn't.
I don't think anyone expects him to be a two way player. They expect him to be a productive offensive player. The one thing the Avs don't really need.
When the Avs needed a goalie, they went out and got a goalie. They paid what was generally acknowledged to be a very steep price for him too, at the time. In hindsight, we robbed the Capitals and contributed to costing McPhee his job.
The point is, we have assets that could be considered very attractive to other teams: 1st round picks in 2014 & 2015 (especially amongst those in the "oh, they'll surely fall back down to earth...next year" camp). They also have 2nd and 3rd round picks as well as a variety of prospects. The quality of those prospects very much depends on how other team's see them and how they evaluate them. I think there's a way to acquire a solid d-man without necessarily giving up a roster player.
Since before the start of the seaon, I've always maintained that you put Tanguay with MacKinnon on the 3rd line, sit back and enjoy the show as they absolutely destroy other teams' 3rd pairing d-men. Unfortunately, Tanguay got injured early on and Mack wasn't ready at the start of the season.
Seriously, we just saw in the playoffs how easy we were to play against with a few injuries. I don't even think a solid 2 line team is the way to go. I'd like to see a playoff series with these forward lines, if everyone was healthy:
RoR-Duchene-Parenteau
Lando-Stastny-McGinn
Tanguay-MacK-Talbot
McLeod-Mitchell-Bordy
Maybe that's not what you go with all the time but to be able to pull this out of your back pocket and keep the other team's guessing is huge. I believe Tanguay can be a similar player to Drouin who can find Mack and set him up all the time. He actually turned Laperriere into a 20 goal scorer the year before he was traded to Calgary playing on the 3rd line.
