Williams is a power forward... period.
T. Jones will be a solid small forward for the next 10 years.
Barnes is probably the most overrated prospect in quite some time. He doesn't look good on or off paper.
Irving is also overrated and has appropriately dropped down my board as I've firmly concluded he is more of a shooter/scorer type point guard than Chris Paul, not that this mattered overall anyway. Cavs just don't need to this guy.
I'm hopeful the Cavs can get Perry, obviously. We get this guy and the Cavs are well on their way to being the type of team that will be a difficult match up for the rest of the league for a long time to come.
If we draft T. Jones, he'll be a solid piece. One that can play for us for a long time. His ball handling and passing ability will be greatly welcomed on this team.
So the top 2 on my board are probably the top 2 on the Cavs board. I'm hopeful we can get Perry, but know for sure we'll have a chance at Terrence with a top 4 pick.
