If we take a bird view, and make a chronological map of who was "the best defenseman in the world overall" in any relatively long window, like we sometimes do for "best overall player in the world", so not a year to year ranking, IMO Chris Pronger was the best defenseman from 2003-2004 to 2009-2010, so between age 29 and 35.
His Norris record in that window is: 3, 3, 5, 7, 8
Lidstrom's Norris record in that timeframe is: 1, 1, 1, 3, 4, 6
And Lidstrom's Hart record is much better than Pronger's.Everything on paper indicates Lidstrom was better.But I don't buy it at all.Pronger was the superior force out there, and the one you wanted on your side in priority.
That window includes Pronger's three spectacular runs, but it also includes three deep runs for Lidstrom.
Despite all of this, I still think Pronger was the top defenseman in the world.
Coincidentally, I think Lidstrom was the best defenseman in the world roughly from age 28/29 to 33/34, about the same as Pronger (and many other defensemen who peaked in their early 30s).
