Though I know it's not your intent, but the statement of Kings option picks are a bit misleading.
Stutzle, Sanderson, and Jarvis were all from the same draft. The Kings could have only taken one.
And while he's not doing great at the moment, I'm still not convinced Byfield was a "bad" pick. Imagine Byfield with the free reign Stutzle had, and imagine Stutzle "needing to learn to check" like Byfield needed to. I just think we're overlooking or underestimating essential factors.
Turcotte hasn't worked out to his draft position either. But nobody was calling for Seider at 5th. Not you, me, or independent scouting services. People wanted Zegras, Caufield, Cozens, or Turcotte (others liked Dach and Byram, but they were already gone). It doesn't exonerate Blake, as ultimately it's the scouting staffs job to do. But Seider at 6th was Wheeler at 5th level shocking.
I just think there's a lot of hand-wringing over picks when the picks themselves have been defensible. I'm not sure why, after years of criticizing development decisions, there's this insinuation the biggest culprit is "bad picks."
The ROI has been bad, but comparing them to other players with different factors at their benefit is missing the big picture.
