Not? Cheaper, better 200ft, produces more, RFA etc. He and Toffoli actually are the only bright spots in Montreal this season. Go check his underlying stats and charts and it should be quite clear he is heads and shoulders better than Foegele, who has regressed for 3yrs now.
Lehkonen has better underlying defensive numbers. That's true.
But "produces more"? Based on what? They are both demonstrated to be 30 point wingers. Over the last 4 years, one guy has Pts/60 of 1.1 to 2.1 and another guy has Pts/60 of 1.1 to 1.9. In terms of on-ice contributions, one guy has 1.5 to 3.2 and the other has 1.8 to 3.0.
I don't know what your "charts" are telling you, but take a look at the raw data rather than someone else's extraction and tell me what you see. I see two nearly identical 25 & 26 year old wingers in terms of production, where one guy is pretty clearly a better defensive player.
That's worth something for sure, they aren't quite equal.
It isn't worth a first, or a Holloway. And the gap between Barrie and Petry right now isn't worth a 1st or a Holloway either. (not to mention, as others have shared, he would NEVER come back to Edmonton)
Combined, the difference between Petry vs Barrie and Lehkonen vs Foegele would be worth a 1st. Leave Holloway out of it.
