Free throw shooting...I know nobody is trying to miss, but seriously, it is not that hard to knock down an open 15 footer 3 out of 4 times. (at least for the majority of the players)
Defense...It's early and obviously it will get better, but we have guys way out of position trying to do too much. Quit trying to block every shot and get in position to get a rebound. Still need to get better at fighting through/around picks, as well as taking charges (That has been a huge part of their success the past couple of years).
Constant Trash talking...A little bit on the court is normal, but finish the F'n play instead of shouting crap out as you release the shot. Every single time some of our guys shoot they think they have to do this. Plus, they look really stupid when they shout out "AND 1", yet can't even hit a free throw...you don't get the AND 1 if you miss the easy shot, so until you can do that consistently, you might want to STFU.
I'm still excited to see the improvement as the year goes on, but hoping it doesn't take too long!
