Yeah, it's really frustrating. When things start getting tight, we've been going straight to iso ball, which just kills our offensive flow.
That is called a mentally weak team. When the game tightens up, they don't persevere with playing the correct way, they panic and go back to what they are comfortable with and to what they are used to. Just like trying to change a bad habit in life, it takes time and patience and mostly constant mental focus - which is harder work than physical effort.
Part of that is on the coach. He has to DEMAND they play the right way and the way that is best long-term for us to win titles with this group. Seems Ime emphasized that on the defensive end, though he was clueless about offense. Now we have what appears to be a good offensive mind in a head coach who is not strong enough to stand up to the players (Brad Stevens II).
