Writing your description, you have given the reasons why the Oilers wouldn't get fair value for these players (if a deal can be done at all.). Eberele at 6m a year, other teams will likely to send money back to Oilers and where is the value for that? And teams with cap and need....well they can likely find better value elsewhere. Pouilet overpaid, and Klefbom, seven year contract: Who wants to commit for that length of term?
Most important player in the cap era.? A GM that knows the cap rules and doesn't fall in love with his own acquisitions.

.

A team like Buffalo may be able to get behind a trade for younger guys like Eberle or Klefbom who could grow with the team. Names on the Sabres that would probably be available are Ennis, Girgensons, Kane, Franson, Bogosian (?)

At this point it's addition by subtraction. Sick of the same old. Soft lazy play mixed with the inability to learn defense and lack of care.
