More on Donatas Motiejunas's case, guess we were not the only one think he has problem back then.
"After the 2015–16 season, Motiejūnas became a restricted free agent. On December 2, 2016, following a prolonged contract dispute with the Rockets which lasted into the first month of the 2016–17 season, he received a four-year, $37 million offer sheet from the Brooklyn Nets, which the Rockets matched three days later. A day after the Rockets matched his four-year offer sheet to retain him, Motiejūnas did not show up for his scheduled physical exam with the team. Motiejūnas' camp made the decision to not report to the Rockets because of a difference of nearly $6 million from the offer sheet he signed with the Nets; the Rockets only had to match the principle terms of the offer sheet, which came to $31 million. As a result, on December 9, the two sides negotiated a new four-year, partially guaranteed deal worth between $35 million and $37 million with bonus clauses. While they appeared to have a new deal in place, Motiejūnas was sent home before the team's game on December 10 after taking a physical, and five days later, the Rockets renounced the four-year deal and their rights to Motiejūnas, allowing him to become an unrestricted free agent."
