Hard to see the Grizzlies pick being better than 10.  Pick 10 would mean the Spurs, Suns, Trailblazers and Pelicans all manage to pass them.  I don't see any of the non-playoff East teams catching them.
I think the pick will be between 11 and 14.  Can a team picking there move up into the top 4 (or top 6, etc?) via lottery?
