They could be a third party broker for teams looking to make trades at the deadline.
For example Claude Giroux, in the last year of His Deal at 8.3 Million. Colorado is interested in Him but cannot absorb the cap hit.
Philly retains 50% and trades Him to Colorado through Buffalo, with the Sabres retaining an additional 50% for a cap pick or prospect. This gets Colorado down to a more manageable cap hit of around 2 million.
The actual outlay in terms of dollars would be around a million for the Sabres, so maybe ownership approves.
Lance Lysowski mentioned a potential one year target for the Sabres in Matt Dumba as a Summer Minnesota Wild Cap Dump at Six Million. He does have a 10 team no trade list, but a chance to play with Dahlin or Power for half a season might be enticing to him. His caveat would probably be he would be moved at the TDL for probably a First with the Sabres retaining salary.
