If you aren't voting for 10 guys I don't think you shoudl. What would make you change your mind on someone's eligibility 13 years later? I think you should have to ustify your picks, including why you think someone is eligible now but wasn't then. If you can't give a solid reason as for why you vote for someone and didn't as well, then you should be eliminated from the panel of voters.
Of course I agree with a writer (I think from Chicago) where they should just ditch the writers voting and the hall just elects people.
