It seems like that. However, we have to wait and see since Valanciunas will try to talk with the Nuggets and tell them that he wants to break his contract. Maybe even pay them to set him free. Also, Monaco's Daniel Theis seems to be with one foot out of the team. If Valanciunas stays with Nuggets, I'm guessing that Panathinaikos will try to sign him up.
Yesterday I read in German news that Real Madrid is very interested in signing Theis as well. Guess his performance in Monaco made several teams having him on their radar. I never understood why he never really got a chance in the NBA, despite being signed for 8 year over there. He is such a versatile big man that get shoot the 3 and give you great defense in the paint as well. Maybe being white and from Europe, while not being a generational superstar, made teams overlook his talent a bit.
Hopefully he can ride out his in my opinion great career at some high level in Europe. Since he seems to have plenty of options, which he deserves, there is more to see from him.
