The Sixers are on the verge of losing another big offseason fish.

First, free agent LeBron James decided to play for the Lakers.

Now, it appears that disgruntled Spur Kawhiu Leonard is headed to Toronto:

ESPN is reporting that the Raptors are finalizing a deal to acquire Leonard in a trade that includes All-Star DeMar DeRozan and could be announced today.

Toronto and San Antonio have been talking about the trade for two weeks, and several incarnations of packages have been discussed, league sources said.

Sources close to DeRozan told ESPN’s Chris Haynes that DeRozan met with Toronto brass in Las Vegas during summer league and was told he would not be traded.

Raptors president of basketball operations Masai Ujiri is taking a significant risk in pursuing the trade. Ujiri will make the deal with a determination that he can sell Leonard on re-signing with the Raptors next summer in free agency, sources said. Toronto would be able to offer Leonard a five-year, $190 million contract next summer. If Leonard left the Raptors, he could sign a four-year, $141 million deal with a team with the available salary-cap space.

Leonard has been clear that he plans to sign with the Los Angeles Lakers in free agency next summer.

DeRozan has three years and $83 million left on his contract, including an Early Termination Option for the 2020-21 season.
