Offer Sheets.
Arguably the most underutilized way for an NHL GM to acquire players.
At this point, I'm sure many are tired of hearing me talk about the lack of offer sheets in the NHL, and my surprise that we don't see more of them. That said, I think there are a confluence of factors this summer that may increase the chances we see an offer sheet, perhaps even involving the Oilers. The UFA pool is lacking in top end RH D, and with a few of the more obvious trade options seemingly, potentially, falling away in the past few days (Hamonic, Barrie, Vatanen), there aren't a lot of quality options for Peter Chiarelli. There are, however, a few teams with promising RFA RH defencemen that might be attractive for a team to acquire via offer sheet, for one reason or another. Ideally a team might prefer to acquire them via trade, but if a deal can't be made, it's not impossible a team looks at the more rare option of an offer sheet. All of Jones, Dumba, Lindholm (LH D, but good enough to be under consideration anyways), Barrie and Trouba are players who may be good acquisitions for the Oilers in the right circumstance, but I'm going to focus on Seth Jones for this article as he probably fits best in terms of being a player of interest to the Oilers while also being part of a team in an unenviable cap situation.
