He has plateaued in recent years from my perspective. He's a decent energy guy - good speed and motor, strong commitment to being on the right side of the puck. But he isn't physical or tenacious enough to be a true standout in that role. Also has struggled in the faceoff circle, which is a problem for the Ducks across the board and almost forces them to replace Lundy with a more proven bottom six C with faceoff ability, if they intend to take a step forward.
Offensively, he was never going to be the most prolific skill player or a true play driver but it feels like offense has become more foreign to him over time. Perhaps something that has been coached out of him to some extent, but he really has shown a lack of feel around the net the last couple years.
I have been saying this for quite some time now but I really think a move to the wing would be best. I do believe somewhere in there is a responsible and hard working two way winger who could put up 30+ points, which is a solid third liner. He needs to be more assertive in driving the net and add more of a physical element, create more space for himself and maybe some offensive opportunities start finding his stick.
There is always the caveat that the Ducks as a whole have spent so much time cratered in their own end in recent years, you never really know for sure what certain guys could do in better surroundings.
