Cleveland could pick up two veteran leaders with rings, be a real contender at the cost of a mid first and early second round pick, I think they do that.
What is that 19th pick to them? They are loaded with young guys that need playing time. Do they want Kyrie Irving to waste two more years while they develop? Plus that 19th pick has guaranteed money and has to be on the roster and they already have the #1 pick coming in. I think they'd consider it. They aren't getting any other Hall of Famer to come to Cleveland.
If you believe the rumors, they really like Sergei Karasev, who is projected around that area in mock drafts. The Cavs reportedly would like to move up to ensure they can grab him, but would probably hang on to #19 and hope he slides if he can't make a deal.
