Brett Brown was upset the Philadelphia 76ers' decision to trade away Brandon Davies in the Andrei Kirilenko deal.
The undrafted second-year player appeared in 71 games over two seasons, averaging 3.8 points, 2.6 rebounds and 13.4 minutes.
"When you start losing people that you are very fond of and have tremendous respect for ... there is a human side of it that bothers me because you are trying to grow chemistry, you are trying to grow a culture," Brown said after Thursday's practice.
"That takes a hit when teammates lose teammates. There is a respect, effort-wise, of how they go about their business. There is a reality to our job that is just business in the NBA, but it doesn't mean it has to feel right."
Davies played in every game before Tuesday, made six starts and averaged 19.0 minutes.
"He is a role player, but we saw him grow his perimeter game," Brown said. "We saw him make some turn-and-face jump shots. He always played with that reckless abandon. He is one of those low-maintenance guys that teams look for who want to have high-character, solid people at the 15, 14, 13 roster spots. I think his better days are ahead of him because he improved with us."
The 76ers could play more small-ball with their makeshift roster.
"There are a lot of moving parts, and there is going to continue to be because it is the nature of our job," Brown said. "Stability is not a word that comes to mind very often with where we are at with the Philadelphia 76ers.
"It is a tremendous challenge to keep the locker room together if they lose a teammate or friend. It is a tremendous challenge to have a semblance of order or purpose on offense or with rules on defense. It is just such a volatile situation at times."
