Kyrie is likely to be ROY this year. He led all rookies in scoring with 18.5 ppg on 47% shooting and almost 40% from 3. I just heard that Kyrie is only the 2nd rookie to ever average 18 and 40% from 3. The other was Larry Legend (21 and .406). Kyrie is 2nd amongst rookies in Hollinger's per stat, behind Faried. Griffin won the award about this time last season, so we should hear something official soon.
