Depends on what is your expectation is when you say productive. If being productive is 60 points, I'll bet money that it won't take until 2032. But it will take until 2032 to determine if he was the best player of that draft.Slaf will be considered a bust if the Habs have to wait until 2032 for him to be productive.
When a team drafts first overall, they're not picking the player so that he contributes in the very distant future.
2032 is very far away. By that point Suzuki, Caulfield, and Guhle might all be retired, President Vance will be running for re-election, my youngest will be in third grade, we might have Mars colonies, and my body mas index might have reached triple digits. We shouldn't have to wait that long.
FTR, Wheeler as late as it took him to breakthrough is 3rd in scoring for that draft class behind two future HHOFers.
