Can the Edmonton Oilers run on Duncan?
More from Travis Yost. Sometimes you have to frame the question a certain way. In light of all of the trade talk surrounding the Oilers and soon-to-be Hall of Fame defenceman Duncan Keith, I think its a critical one to answer. The rumour mill has been flush with speculation over Keith, with a lot of the discussion centered around how much the Oilers should be willing to pay for a player at the tail end of his playing career. Ultimately, we dont know where the asking price for Keith and the final year of his contract will land. The bullish case  the one the Blackhawks are surely selling  is that there are still miles left with Keith, and that much of the overarching performance issues are a byproduct of the team around him. The bearish case is that Keith was a primary contributor to Chicagos struggles. A few key points here:  - Keiths salary ($2.1 million) is dwarfed by his cap hit ($5.5 million);  - The Oilers (or any other team) could negotiate a trade where the Blackhawks retain up to 50 per cent of the players salary (including bonuses) and cap hit, but no higher than that; and..  - The Oilers have cap space today (approximately $16-million) to leverage, but also have 8 unrestricted free agents and 3 restricted free agents in need of new deals  The point being: Edmonton is in a tricky spot here. General manager Ken Holland and the rest of the Oilers organization have mounting pressure to deliver a true contender. The team has some cap space to play with, but its limited, meaning opportunity costs will exist. Im using Goals Above Replacement as a proxy for player production here, but other measurements show a similar (and deeply discouraging) trend. I also think its worth juxtaposing this against a player like Patrick Kane  another veteran Blackhawks skater, also playing tough minutes with a depreciating team,  Over the last three seasons, Keith (anchoring the teams top defensive pairing) and Kane (a fixture on the teams first-line) have played 1,500 minutes together. Thats a lot of time, but its also in line with what we have seen from Chicago for most of the past decade. Because Chicago has been so dynastic (and so consistent) with deployment, we can see how their best units have fared together over the years, and then look again at how they performed when split apart. Pay particular attention to Keiths numbers here:  Perhaps Keith can no longer play the tough minutes the same way some of the other Blackhawks veterans can, but there is increasing evidence hes no longer driving positive performance. Expecting any 37-year old to be productive with this many miles on his legs seems unrealistic, but the reality is an Edmonton trade would see him as a regular fixture in the lineup irrespective of what they offer. There is something else that I think is worth addressing. One of the arguments I have read over the past week is that while Keith isnt the player at 37-years of age that he used to be, he could still add value in lesser minutes in more of a depth defensive role. Until we see that in practice, its somewhat hard to argue. But if we look at Keiths performance relative to calibre of opponents over the last three seasons, we see two things: Keiths play was noticeably better against weaker competition, but the Blackhawks were still in the deep red. And just to eliminate the possibility of goaltending diluting the data in either direction, we can use expected goals to illustrate the same point:  Keith is a Hall of Fame defender and its certainly within the realm of outcomes that he has a bounce back season of sorts playing with better teammates around him  and theres no better teammate in the world right now than Connor McDavid. But the Oilers organization is trying to figure out how to inject talent into the lineup to deliver a more competitive roster. Its hard to see how Keith provides help on this front, even if they can trade for him at a fraction of the cost. A fantastic player in his prime, but that prime appears long, long ago.
