One thing I find interesting about this deal is that pretty much every other player besides Malkin and Toews/Kane is making 8+ million to be THE guy. Drai doesn't even need to be THE guy most nights. He just needs to be able to run a second line effectively.
So you have to ask, what is Drai's job? What do bar do you set for him? I could see a future where he puts up around 65-75 points per season as an effective second line centre, with McDavid putting up 90-105 points pretty easily, and the team succeeding. Is that good enough?
Basically, if the team continues to put up 100+ point seasons even if Drai is only putting up 75ish points, is he worth it? I would say yes.
Most of the talk on related to this contract has been about Drai being able to replicate his 77 point regular season. I really don't think that matters as much as his playoff performance does. This is a team that should be expected to finish top3 in the division for the next 5+ years, and I think anything less would be a total failure. I think they get in regardless of whether Drai puts up 70 or 85 points.
We can probably get away with the offence going primarily through McDavid in the regular season, but that is not so in the playoffs, as we have seen.
So,where this deal will look great, or not so great, is in the playoffs. If Drai can do damage on the opposition's second pairing, as we saw this year, then he will be worth every cent of the deal.
