Tatum is 9-13, yet I only remember him shooting a couple of times lately. He simply has to be more involved in the offense, especially when he's so on like he is tonight. Kyrie is 9-24 right now, but it's hard to blame him because he's also the only one who is aggressive in getting his shot.
There's definitely chemistry issues with this team and a lack of understanding of roles. And that is on the coaching staff to fix. That we have not improved in this chemistry/clarifying of roles regard in 20 games is such a failure by the coaching staff.
