Bynum decided Wednesday to join the Cavaliers on an incentive-laden, two-year contract, sources told ESPN. However, GM Chris Grant was unable to address Bynum's addition as the sides are still hammering out the deal.
Bynum's deal is worth up to $24 million, sources said, and the Cavs hold a team option for the second year. Only $6 million of the contract is guaranteed, according to sources.
While he works on closing Bynum's deal, Grant said he's excited to add players who bring toughness, leadership and playoff experience to the Cavs' young core.
"We spent a lot of time debating and talking about these two gentlemen here and how well they fit into our organization," Grant said. "We're very happy to add both of these true professionals to our team."
Jack, who signed a four-year, $25 million deal, said of Bynum, is excited about impending addition of Bynum.
"An anchor in the middle is something every team is desperately in need for and when healthy, he's one of the best, if not the best big men in the game," Jack said. "If we're able to lock it down, and make this thing come to fruition, I think he definitely helps take our team to the next level -- and if he's able to stay healthy, obviously."
