As an Avs fan, I'd say you want Rene Bourque for the price of a 3rd line winger (on a good team, maybe around a 3-4th round pick), Comeau who wasn't mentioned brings some good hustle and physical play to a 4th line so worth a late pick, Mitchell is done so you wanna stay away from him, Tyutin is a #6 or 7 dman so don't waste a pick on him, and Iggy is a wildcard. He obviously won't be great but he won't look as bad as he does on the Avs. If you're acquiring him exclusively for goal depth and are badly lacking in veterans + wingers then might be a gamble but only with salary retained and not as your main trade deadline acquisition.
I have low expectations on any return for them so I'm being honest and not trying to be a homer in any way. I'd say Bourque is better (at least this season) then people are giving him credit for, maybe Comeau as well, and the rest are all pretty much worse than how you remember them (including Beuchemin).
Edit: Weircoch isn't bad for a #4-5 dman and as playoff depth in case of injuries, might find some success like Nick Holden has with the Rangers and Holden looked a lot worse last season than Weircoch does now. I'm not sure if he's on the trade block though cos of the whole expansion requirements.
