It’s that time of year again, no, not the holiday season, I’m talking NBA trade season. Dec. 15th was the date that players signed in the summer of 2018 could be traded. We already saw our first move when the Wizards moved Kelly Oubre and Austin Rivers for Phoenix’s Trevor Ariza. The Cavs are in full sale mode, and they’ve got an asset most everyone wants: 2019 cap space. The Cavs have $32.8 million in salary that expires this year, with J.R. Smith’s 2018 salary guaranteed for only $3.9 million in 2019. There are quite a few trades that the Cavs could execute to help teams clear the decks for the biggest free agency summer since 2015.
