Take out dell and lehner and karlsson trade makes sence
I think Dell is a central component to the deal. The Isles need defense and goaltending. The Isles were 7th in goal scoring, and while losing tavares will be a big hit to that, clearly scoring was not an issue. However, they were dead last in goals against. Griess was awful, and Lehner, on a one year deal is not a likely solution. I know Dell is not a solidified goaltender, but he would seem to be a big upgrade over what they have now.
Further, they need good D. They have young forwards, but little on the back end. That's why I wonder if Roy and Dell are enough, and whether a guy like Ryan or Dillon might be needed instead.
Either way, I think Dell would be a centerpiece. Karlsson would be a cap swap for the sharks as they would have alot of trouble keeping Lee long term (always the plan on younger deadline acquisitions) with karlsson's 2M the books in 2019-20. Also, karlsson's specialty is killing penalties and defensive play, so he would fit the mold of a forward that the Isles need.
Basically, it would be the sharks getting a physical top 6 forward for a potential #1 goalie, a top defensive prospect, a better defensive forward and penalty killer, and a top pick. Fits the needs of both teams as the sharks are clearly in the market for a difference maker at forward, while the Isles have gotta be looking to solidify their back end.
