Was thinking of 10 minutes per pick for the 1st round, to allow for trades.
5 minutes per pick in the second round. That would equal 300 minutes, or 5 hours. Not too long to deal with.
Would rather hold it in one day, here on the blog.
I can accept lists for those who can't make their appointed time, if a proxy can't be found.
As usual, I would immediately assign highest remaining player, based on the results of the actual NBA 2011 rookie draft, to anyone who missed their pick.
