I love Lidstrom, but I'm gonna state the obvious here.
When Lidstrom was in his 30s, his competition for NHL Dmen was really weak.
When he was younger, he lost to Bourque, Coffey, MacInnis, Leetch, Chelios, Blake.
But as he got older his only peers for nearly an entire decade were Pronger and Niedermayer (who's play declined WAY earlier than his). And even Niedermayer wasn't effective for half the decade, as his primary skill of skating was stifled behind the New Jersey Trap/DPE , and was only unleashed after the 06 lockout when he was already 32.
Neither of their games really aged as well as Lidstroms.
Suter/Weber/Chara/Keith/Doughty were still new and just starting to come into their own, and hadn't really firmly entrenched their dominance.
For 11 years, Lidstrom was pencilled in as a Norris Finalist before the season even started.
Here are who Lidstrom was a finalist against by year:
2011 - Weber (nearly won it by a single vote) and Chara
2010 2009 - Did not win, but the winners and finalists were Chara + a 26 year old Keith, with Mike Green being a finalist twice.
2008 - Pfaneuf (lmfao) + Chara
2007 - Niedermayer + Pronger (they had their votes split as they both played for Anaheim)
2006 - Niedermayer + Zubov
2005 - Lockout
2004 - Niedermayer won
2003 - 39 year old Al MacInnis + Derian Hatcher (lul)
2002 - 40 year old Chelios who was also his team mate (lmfao) + Blake
2001 - 40 Year old Bourque + Scott Stevens
Lidstrom had such low levels of competition for that trophy for a VERY large window. A bunch of 40 year olds for the first half, and Chara+Green for the last bit.
