Here's the production of the main scoring line forwards for the Avs.
*PDO and Corsi numbers taken from Extraskater
Duchene - 71 GP, 70 points, 100.1 PDO
Landeskog - 81 GP, 65 points, 103.8 PDO
O'Reilly - 80 GP, 64 points, 100.3 PDO
Mackinnon - 82 GP, 63 points, 103.3 PDO
Stastny - 71 GP, 60 points, 101.7 PDO
Parenteau - 55 GP, 33 points (Im assuming hes going to be traded to be honest)
Needless to say, an incredible year by the Avalanche. However, their team PDO (102) and S% (10.1) are both 2nd in the league but theyre also 25th in the league (47.4%) in corsi so theres a reasonable chance theyre in for a significant drop in production due to being slightly less lucky. This would mean lower totals for everyone and theres a big difference if a player puts up 55 points rather than 65.
Now with the assumption that their team production will go down, who do you think will be most affected? It would require being a top 7-10 scoring team in the league to have 4 forwards (let alone 5) score 60+ points each.
Duchene and O'Reilly have a neutral PDO so their production should be stable.
Landeskog seems like a sell-high candidate as his shot rate and on-ice s% are both high.
Mackinnon would also appear to be a sell-high candidate but given he's a rookie due for growth and his improved 2-way play in the second half he may be able to keep it up and possibly improve
Stastny's PDO is slightly high and if treated like a 55-60 point center he should be fine (instead of his 69 pt pace this season).
