I think O'Rrilly has been the best forward on the team over the last 3 weeks or so, though Dutchy was the best for the first 3 weeks or probably longer. It's a tie, they both lose.
People will say Duchene has been worse though because it's hfboards and nobody remembers what happened in the past.
Or because people can combine the past with the current, and some actually value defense. I'm not saying you don't, not sure where you stand on that subject actually, but some people really only judge forwards by their offense. I admit I probably value D too much- to me it's just as important. When looking at the season as a whole RoR has had the better season to me.
Duchene has only 2 more points on the season, which really should be the same (RoR got screwed out of an assist early in the year when they took back that one goal that bounced off Everberg which they claimed was tipped in by a high stick by RoR, and a couple weeks ago Lando go credit for an assist when it was actually RoR who tipped the puck as it wrapped around the boards, not Lando). RoR has been a part of more goals scored (little things that don't pick up a point but still lead to a goal) but Duchene has more of the key plays leading to goals. So, all in all, offensively they have been equally as effective to me.
Defensively, it's not even close. RoR and Lando are easily the best defenders on the team. Big gap from them to anyone else.
Combine the 2 aspects, offense and defense, and RoR is having the better season as a whole.
