I don't have any problem with Smart's ranking. What is the difference between 20 or 23 or 26 or 29? Not much. I look at it as more of a range or a tier. Right now he is in the bottom tier of starting PGs but that is not bad for a rookie these days.
And Rondo? Also about right. I look at the first few above him, Hill, Walker, Holiday, Lawson, Bledsoe; and I feel like Dallas would probably rather have these guys over Rondo but not a big difference. Of course that is regular season Rondo, not playoff Rondo.
