There's been plenty of rumors floating around with talks of the team trying to acquire Jakob Chychrun, Erik Karlsson, John Klingberg, or even Patrick Kane.
I think Holland is trying, but like many team's Holland is simply handcuffed with the salary cap and being unable to trade Jesse Puljujärvi, doesn't help the Oilers cap situation. If the Oilers want to make a move they will likely need to bring in a 3rd team to retain salary.
