Thank you for the appreciation. Should have been more expansive. Also will tie my comments with the focus of the thread.
Chronology of the Hart Trophy winners:

Note that all four of Shore's Hart Trophies come immediately - 4 in 5 seasons after the introduction of the 1932-33 NHL Salary Cap which
also featured a reduction in roster size. Net result was that the league turned to hybrid players, playing a forward position and a defence position. Three of the Hart's after Shore's string were won by such players - Babe Siebert, Ebbie Goodfellow,Tommy Anderson. Other star players also became hybrid players, namely Dit Clapper. Effectively teams were getting two roster spots but paying for one.
The AST nominations have to be viewed in a similar light with an added twist. List follows:

From the AST list you will notice that some of the hybrid players were AST defencemen. Babe Siebert, Goodfellow, Clapper. The twist is that during the thirties the 1st and 2nd team did not represent the top four defencemen as is the case for nearly the last eighty season, rather the voting was for the top RD and the top LD, with alternates - 1932-33 results here:

Shore being a RHS benefitted from a few favourable convergences.
Comparing Hart's and AST's across eras is tricky. You are a counter. Direct or indirect, matters little.
The only hybrid player today of note is Brent Burns who started as a forward and converted. Latest Norris winner but at what cost in terms of previous ballotting.
Likewise in the context of the Hart and AST voting involving Sidney Crosby. Does Crosby benefit from the favourable AST and Hart convergences that Shore did. How does the Norris impact perceptions of the Hart? Keep in mind that Red Kelly was more of a hybrid player with the Red Wings than previously believed and this had an impact on his AST and Norris awards. This may not seem important but when Ron Stewart of the Leafs, normally a RW played a good half of the season on defence it was reflected in the 1st half AST voting:

Which brings us to the final point is that the voting has varied in format over the years. Half season and end of season voting vs end of season, media vs coaches, other nuances.
All these factors have to be considered beyond counting.
