An honest(and what I consider fair) assessment:
Strong FO. Had breakaway(drew penalty), backchecking, etc..
I mean, these are good basics in helping the team win. I HOPE many would agree with that.
The problem is, he's an offensive player or well...is expected to be one. He can be a good team player, win faceoffs and do all that stuff but grinders do that and get paid less. DD gets paid 3.5 mil because he's expected to produce. He's not expected to produce 60 points again but guy should be hovering at around 0.5 PPG. 35-45 points a year, winning faceoffs, backchecking, using his speed, etc... In that case, it would be good.
35-45 points with no hustle, no faceoffs is no good. At this point, asking for 35-45 points is asking for an offensive top 9 player. Which is reasonable, but you'd expect them to contribute in other ways as well. You'd expect them to draw penalties, to win faceoffs and do some little things.
Will DD ever be a two-way force? Nope. Does he have the capability to produce 0.5ppg and win faceoffs, create chances, etc... I think so BUT he isn't showing it. He had some average games, he had a very good game but he's had some bad games too. The guy is struggling. I don't foresee him being on a year long cold streak but consistency is important. We need players to be somewhat consistent(not expecting a point every game or whatever but the chances, the drive, etc... need to be there). He's got the hustle there, not the results. Results matter.
