You're right Spinner. Its been a long-standing problem for the Sixers. Bairstow might be the first half-decent screen-setter we've had in 15 years! DJ has improved to just ok in the last couple of years, but its still nothing special. Sotto OMG, the guy almost takes off for the basket before he sets the screen!
Some of it is a failing of Joey Wright, because he either never wanted to run any significant screen action for shooters, or he was unable to teach his team to execute it properly.
Another reason would be that we haven't had a good shooter on the team for long enough to build familiarity with DJ or any other big, so that they can confidently read what each other is going to do in a pick and roll situation. Just getting reps on that with Dusty and DJ/ Bairstow would do the offence the world of good.
I think the key message here is continuity of coaching and core personnel is what is needed at the Sixers right now. CJ got his feet under the desk way too late to prepare our largely new team and it shows.
Its gonna be ANOTHER year making up the numbers. Gotta give CJ another full season after this and see if he is making progress. Hopefully he will have full control over next season's roster construction too. Starters are ok, but the entire bench is a liability so far this season.
