One habit I wish Brad would stop is to not try to save guys when they are heating up. You ride a hot player out, and don't kill their momentum by taking them out. He is a little too quick in this regard.
Yeah, this kills me. That being said, I think he’s doing better in this respect compared to last year
Yeah, I'd go along with this as far as a coaching issue. as for the OP's issues, don't agree with them at all except the Tatum one where he drives into a crowd but that would apply to everyone on the team.
The other coaching things that I think need improvement:
1. holding Timeouts until the end of the game instead of using them to disrupt runs the other teams are having. Other coaches do it to the C's with a pretty consistent effect and it's been done for decades in the league as a proven method for breaking runs most of the time. Makes no sense to have 4 timeouts in the last 5 minutes of the game if you've let it get away from you and you're in a double-digit hole that you might have prevented by calling a TO or two sooner to stop runs.
2. the live-or-die-by-3's offense. hate it with a passion. we're not as bad this year as we've been the past few years but this team gets 3-happy and on a cold shooting night they're digging a hole so fast it's head spinning. need to develop smarter offensive strategy of driving, cutting, passing for easier baskets than 3's. Team needs to learn a made 2 pointer is more points than a missed 3 pointer. getting a couple made baskets under your belt when struggling from deep can help get a shooter on track. might also increase foul calls in close to get to the line for easier points and help loosen up opposing defenses that are in foul trouble.
as for player habits, I'd fine every player dumb enough to not have enough court awareness to know where they're standing and thus step out of bounds when catching a pass or taking the first step on a drive. I swear we have to be the biggest offenders in the league on that.
