This is an update and expansion of Sturminator's thread. This was the criteria Sturminator used: I agree with Sturminator's reasoning and tried to keep his standard when possible. Two exceptions: 1) When extending the records backwards, we only have points totals, not complete voting records. When only point totals were available, I included all defensemen who received at least 2 voting points. 2) With expanded voting records in modern times, I changed the standard to include all defensemen who achieved at least one first place vote or two top-3 votes AND any defenseman who finished ahead of them in total points. Example: 2008-09 Norris voting. Sturm's original standard worked for seasons in which writers only voted for the top 3. But with votes down to top 5, it doesn't make any sense to me to exclude Mark Streit, who actually appeared on more ballots than the 5 guys under him who do meet the original standard. Here is the data, sorted alphabetically. I believe we have full records for every season since the Norris was first awarded in 1953-54, except 1954-55 (only top 6) and 1976-77 (only top 5).
