Thing is, Bourque beat Chelios repeatedly for the Norris when they were both in their prime. Same with Coffey. Look at the Norris record, it goes Coffey->Bourque->Chelios->Bourque->Leetch->Chelios->Bourque->Coffey->Chelios->Leetch (bolded are the first overlap years with Lidstrom and the rest of the list). Then, at the "end" of all of their careers, and after MacInnis was over the hill as well and got his Norris, Lidstrom turned 30 and started winning Norrises. Even Rob Blake and Leetch were into their 30s before Lidstrom started winning Norris trophies. Think about it for a second: Lidstrom won his first Norris in '00/01. Bourque retired that year at age 40. Coffey retired that year at 39. Chelios somehow didn't retire, but he was still 39 (and missed most of that season with a knee injury). The remaining "top guys"? Blake, Leetch, and MacInnis, all in their 30s (and MacInnis just a couple of years from retirement), plus Pronger. How does this possibly constitute anything close to "the same" competition during the overlap?
So yes, there was overlap indeed, with Bourque playing against those guys at their best, and Lidstrom playing against those guys at the end of their careers. So if the major offense is being taken by the phrasing of "Lidstrom faced weak competition", let's all just look at it instead from the perspective that Bourque simply faced more difficult competition, and avoid "slighting" Lidstrom.
And also, I don't know if no one started giving Stevens any credit for his talent before he had Cup rings to go with it in New Jersey, but he was awesome with Washington, even if he WAS even better in New Jersey. Larry Murphy is in the Hall of fame, and was only in his mid-20s at the time, and he and Stevens flip-flopped as the top scoring defenseman on the Capitals for a few years, and next to only Mike Gartner as the team's leading scorer. That's fairly impressive right there.
