Everyone loves the chance to bring up Barzal. Get over it, B's didn't choose him and there are reasons why.
Barzal, for being over a PPG, has 5 goals this season. and has 31 goals in 119 games. Senyshyn has 36 goals in 86 games. Barzal also has dealt with some injuries already in his young career.
Also, Bergeron was exactly 1.00 PPG in his junior career. Jeff Carter; just over a PPG at 1.04. Milan Lucic was a 0.65 PPG in juniors; I'd say he turned out alright. James Neal (0.93 PPG), Ryan O'Reilly (0.91 PPG), Scott Hartnell (0.99 PPG), Andrew Ladd (0.88 PPG); Shall I continue?
The main point being, who cares what you put up in juniors. I'm sure there are loads of players who were over a PPG in the CHL that never panned out. Instead of just stat watching, watch the player.
As for defenseman, scoring is the last thing that should be a go-to for how they're developing.
All I say is that while there was some solid argument last year about Senyshyn production justifying picking him high (limited minutes, great 5on5 per playing time output), this season he is the one to carry the load and he is at 0.75 PPG in his post draft year (for now, this is why I wrote he better turn it on). This absolutely should be a concern.
Also, I will go all the way and destroy every single one of your examples:
- Patrice Bergeron went straight to the NHL after his draft, and posted his 1.0 PPG in QMJHL in his pre-draft and only year there (and 4 games he played the year before). I'd say you'd have a very hard time arguing he would be below PPG in his post-draft season.
- Jeff Carter was over PPG in his pre-draft and post-draft years. While he did not exactly destroy it, his overall low 1.04 is a result of his first OHL season where he was 16. Again, Senyshyn is 0.75 in his post-draft year alone, without previous seasons.
- Milan Lucic is a terrible example because he is a completely different player with other qualities, and even he himself exploded to become a PPG player in his post draft season while destroying WHL on his way to Memorial Cup. I think we are safe to say this is not going to happen with Zachary this year.
- James Neal is a better example how it could turn out, I give you that, but even he had 0.88 PPG in his post-draft year, he was also one of the youngest players in the draft, 6 months younger than Zachary, it also can be a difference at such career stage
- Ryan O'Reilly is the same story as Bergeron. PPG in pre-draft year, straight to the NHL post-draft. Terrible example, nowhere close to the Senyshyn case
- Scott Hartnell... I don't even know what to say.. 1.32! PPG pre-draft year, straight to the NHL post-draft. Are you serious?
- Andrew Ladd was well over PPG pre-draft, also his first year, best rookie in his class. Led the league with +39.Took a huge nose dive in production in his post-draft year, thats true (but his complete team did too), and was basically an enforcer that year, having almost twice PIM time as the goons on his team.
So excuse me that none of your examples are anywhere close to be reassuring. High draft picks, especially the ones blessed with blazing speed and not iron fists are not supposed to post 0.75 post-draft. This is the only reason I brought up Barzal, because he actually delivers right now. I don't give a **** about him, I want Zachary to justify his draft position and not getting outscored on his team by a 17 year old rookie who isn't supposed to be picked before 3rd round right now.
