i'd like to know that too.
i think you're right that it's probably easier for a doughty or keith to be in the CS conversation (vs hart consideration anyway). but when push comes to shove, we still see j williams over doughty, c lemieux over scott stevens (and goring over potvin, though admittedly i didn't watch that one). at that point it's not even omg points, it's omg memorable goals. and i think it's fair to say that the CS hierarchy goes 1. franchise forward or bobby orr, 2. goalie, 3. buttload of goals, 4. captain or inspirational leader who isn't the clear best guy (messier, toews, niedermayer, crosby #1, ovechkin), 5. complementary player who scored a lot of big goals, 6. franchise d
here's my accounting, with snubs or guys whom we assume would/should be close calls in parentheses and the guy who won it over them:
1. beliveau, orrx2, lafleur, trottier, gretzkyx2, m lemieuxx2, sakic, yzerman, malkin, crosby #2 (gretzky/messier, modano/nieuwendyk, sakic/roy #3, kopitar/williams)
2. crozier, hall, parent x2, dryden, parentx2, smith, roy #s1-2, hextall, ranford, vernon, giguere, ward, thomas, quick (belfour/nieuwendyk, roy/sakic, brodeur/giguere, giguere/niedermayer, holtby/ovechkin)
3. cournoyer, leach, bossy (bossy/smith, kurri/gretzky #1, mullen/macinnis, simpson/ranford, k stevens/m lemieux #2, the only case i can think of where buttload of goals was trumped by anything but franchise scorer or goalie is maybe gaborik/williams)
4. keon, messier, roy #3, toews, crosby #1, ovechkin (clarke/parentx2, messier/leetch, brind'amour/ward, chara/thomas)
5. goring, c lemieux, nieuwendyk, williams (honestly can't think of a time when a clutch secondary guy was robbed, maybe marchand/thomas but i don't think they were reasonably close at all)
6. robinson, macinnis, leetch, stevens, keith (potvin/4 guys, s stevens/c lemieux, lidstrom/yzerman, niedermayer/giguere, pronger/ward, pronger/niedermayer, lidstrom/zetterberg, keith/toews, doughty/quick, keith/kane, doughty/williams, maybe letang/crosby #1, not because letang was so great but because that CS was so weak)
7. (run of the mill top scorers) richards, zetterberg, kane (macleish/parentx2, bossy/goring, fedorov/vernon, kane/keith, kessel/crosby #1, malkin/crosby #2, kuznetsov/ovechkin)
8. (specialist) gainey (pahlsson/niedermayer, bergeron/thomas)
9. (no idea how to place) savard
caveat: the big special case here is if a player has already won one. then the voters are very careful to give you a second one.
i think what we learn from this is that your franchise scorer having a great playoff run is almost never going to lose the CS unless he's a grey area franchise scorer and maybe could go in run of the mill leading scorer (modano and kopitar) or everyone goes insane (gretzky). there also aren't a lot of years where you could say a goalie deserved it but didn't win it; there are way more years, anyway, where a goalie was a debatable choice. captain/leader and clutch secondary scorer are also overrepresented, with few snubs.
past a certain threshold, buttload of goals is always going to beat any category below him. the only exception is mullen/macinnis. but i think maybe i also should have made a special category between goalie and buttload of goals for defensemen who lead the league in scoring, which is a very short list: orr (doesn't count anyway), robinson, macinnis, leetch, niedermayer. and niedermayer was only beaten by one of the most phenomenal goalie playoff runs of all time.
which is all to say that if you look at all the snubs and close calls, defensemen (esp defensemen who don't heroically lead the league in scoring) get the short end of the stick more than any other category of smythe contender. to a point, i do think i also value a franchise d more than the average observer.
