Who do you think the Cavs should take Kyrie Irving or Derrick Williams?

Noo they need Kyrie Irving...Derrick williams is a sf/pf big man...the cavs are stacked with big man so mostly likely he would be helping varejao in the paint but thats where j.j hickson and Antwan jamison comes in at the pf spot and both are better than williams. You simply cant past up the talent of irving .
