One wonders if we should have just kept Hyman instead.
5.5M AAV Hyman with Edmonton: 175 GP, 75G, 84A, 159Pts
Since Hyman left:
11.64M AAV Matthews: 166 GP, 114G, 98A, 212Pts
10.9M AAV Marner: 171 GP, 70G, 146A, 216Pts
6.9M AAV Nylander: 182 GP, 86G, 108A, 194Pts
Note that I'm not calling Marner lazy or anything like that. If anything, he tries too hard to solve problems the fanciest possible way. When there is no space, the game gets very basic and if you're on the wing and you're the third or fourth shooting threat on your line, you have to help get the puck back.
One thing that should help Marner excel again is adjusting his puck carrying more into his hip pocket, not out a full stick length in front of his skates.
