Patrick Marleau, Joe Thornton, and Evgeni Nabokov are the standards - both Thornton and Nabby were at the game last year (Nabby was the only goalie who didn't let up a goal). Newcomers Dan Boyle and Rob Blake are also on the ballot... my vote's for Boyle, of course (nothing personal, Blake).
You can read all the official stuff here.
Now, since the above options were selected before the season got underway, the obvious Shark missing from the nominations is Devin Setoguchi, who leads the team in goals (and is right behind Marleau for points, as of last night). Two other candidates (both forwards) - Joe Pavelski and Ryane Clowe. Milan Michalek is not far behind. Christian Ehrhoff has been reinventing himself as of late, too...
So, if you're like me, and you're p.o.ed that Gooch et al. are not printed on the ballot, you can start your own write-in campaign.
At the risk of sounding self-important, I would like to invite all and sundry to work with me on a coordinated write-in campaign. Gooch, Pavs, and Clowie. In that order.
Who's [not "whose"] with me?
UPDATE (7:30pm) = Mike Chen is with me!
