The 21st pick for Smart I think is laughable because I indeed laughed when I read it. But I'll play along with the theme gauge the players based on picks and what's available this draft.
IT, 5-9 preinjury. 8-12 now
AB, 8 to 12
Crowder, 9-14 (contract adds value)
Horford, 13-17 (contract hurts value)
Smart, 11-16
Rozier, 16-20
Brown, 2-5
KO, 25-30
Zeller, 45-55
I feel ranking this years draft the picks in this draft are likely to yield the following
1= All star
2-8= potential all star
9-16= starters
16-22= role/rotation players
23-35= bench players
35-45= end of bench players
45+= d-leaguers.
