With two roster spots open, general manager Danny Ferry is still shopping. “The Cavaliers have been in talks with free-agent center Jahidi White for much of the summer and hosted him on a visit last month. They’ve also been in touch with free-agent big men Christian Laettner and Andrew DeClercq among others. Several other free agents have come to Quicken Loans Arena to work out in recent weeks, among them former Utah Jazz center Ben Handlogten” Brian Windhorst reported today.
