Yes you can re-negotiate contracts in Europe. The year before Bogdan went to visit Phoenix. They were keen to get him over for season 2016-2017. He just came off a disappointing final 4 in Euroleague with Fener falling short of winning the title. One thing he wanted to do was win Euroleague title before he leaves for the NBA. He has won everything else there is to win. Suns didn’t like his decision and cried foul.
Like I have said in the past, I have known Bogdan since he was a kid. Followed his career from his early teenage years. One thin that kid always wanted to do was play in the NBA. He left a mark at Partizan before he left for Fener. He won everything he could except Euroleague with Partizan.
When he was leaving Partizan, he had much bigger offers from other European teams but he chose Feber because he believed that was his best path forward in terms of development for hus NBA career and a chance to win Euroleague. He chose his teams and coaches carefully to reach his goal. At Partizan he had a legendary coach in Vujošević who is known for developing young players into very good players and getting the absolute maximum out of his team. At Fener he had a legendary Serbian coach who has won a Euroleague title with every team he coached in his career and who is also known for developing young player. Both coaches originate from Partizan.
He was never going to be one of those players who saw the money in the NBA abd left as soon as they got drafted without being ready. His career has always been about playing in the NBA for a few years. He idolized Kobe Bryant and loved watching the Spurs play because they play basketball the way it should be played (i.e. there is a lot of European type of basketball with the Spurs)
In short Phoenix, jumped at the shadow and got mad because he wanted to wait an extra year. Vlade saw an opportunity and jumped at it. He had some inside knowledge there and he played those cards right. Bogdan was ALWAYS going to play in the NBA its what he strived for since he was a kid.
