I think, as fans, we need to look in the mirror. I personally had unrealistic expectations of this team. In. Retrospect we should have expected growing pains in the early part of the season. Integration of 2 players coming off of injury, young players adjusting to new roles, with the reintegration of the injured veterans. Both Brown and Tatum are being asked to take on supporting roles to Kyrie, and Hayward, after being alpha players late season and in the playoffs.
The team is over .500 after a rough early season schedule and lost to Utah, a likely western playoff team on the second game of a B2B after an overtime victory over the best team in the east. That's disappointing, especially at home, but no reason to panic and not completely unexpected.
I preach patience.
