And the best part is.
Backstrom. Ovy
Crosby. Malkin
Mcdavid. Draisitl
Matthews’...... Hyman. Brown. Kapanen. Johnson ennis. Nylander
Another thing:
PP time/82 games vs. On-Ice GF/60 in career
Crosby: 347 minutes; 8.7 GF/60
Ovechkin: 371 minutes; 9.0 GF/60
McDavid: 258 minutes; 8.2 GF/60
Malkin: 361 minutes; 8.9 GF/60
Backstrom: 288 minutes; 10 GF/60
Matthews: 201 minutes; 8.4 GF/60
If Matthews played as much as McDavid on the PP (who is second lowest), he's generating another 8 goals on the PP per 82 games. Bump that up to Ovechkin #'s and you are essentially getting an extra 17 goals. Now not all of those goals will go towards Matthews' production, and that means other guys (i.e. the 2PP) are not producing as much (assuming the Leafs receive the same total amount of PP time), but Matthews' numbers only start to look better.
Another thing is that McDavid and Matthews have not even hit their primes yet, while the GF numbers for the other 4 have all of their prime years in it already. It is going to go downhill for them very soon, while for McDavid and Matthews, it's only going to get better.
