NBA free agency officially began Monday, and the first stunner came the following morning when Myles Turner, the top free agent on the board, agreed to join the Bucks on a four-year deal. That's a surprise on its own.

A former LeBron James teammate from the Los Angeles Lakers was reportedly linked to the Dallas Mavericks for the upcoming NBA season, as the team looks to fill the absence of Kyrie Irving.

While they lose key players, the Mavs still have four former No. 1 picks, a rim-running center in Dereck Lively II, another guard in D'Angelo Russell and key wings in Naji Marshall and Max Christie. That's a championship roster.
