If Sydney makes lineup changes it could make a big difference. Just like United's recent changes have. David Andersen's advice was gold- it's nil all right now.
I'd start with Newley or Didi into the starting 5 for Cooks or Lisch, to get the offense going.
Cooks plays off others, like McCarron and Barlow do for United. He's passive. Lisch is working his way back and hasn't scored more than 2 field goals in any of the last 5 games since his return. They need another guy who can push the ball, attack the rim, apply scoreboard pressure.
I wouldn't make too many changes with only 3 days between games. But, think outside the box. Only Casper and Tate should be considered untouchable for starting spots on Thursday.
