07:05 AM ET 07.08 | What's next for free-agent center Andrew Bynum? The Cleveland Cavaliers have joined the Dallas Mavericks as a prime team to watch in the race to sign [Bynum]. Sources close to the process told ESPN.com that the Cavaliers are legitimate contenders to sign Bynum after his lost season in Philadelphia, especially if the former Los Angeles Lakers All-Star is willing to sign a one-year deal. Initial indications are that the Cavaliers won't offer more than a one-year deal to Bynum to preserve all of their projected salary-cap space in the summer of 2014 and the expected free-agent pursuit of LeBron James. But Cleveland does still have roughly $15 million in available salary-cap space to use this summer and, sources say, they have legitimate interest in Bynum.
