To judge from last night, the starting lineup might be:
Schröder, LaVine, DeRozan, Isaac Jones, Eubanks.
It helps that Jones was 4-4 last night with 3 rebounds, 2 assists, and a block. But I imagine that the coaching staff will be evaluating everyone's performance in detail, in terms of replacing Murray and Sabonis. Coach Christie has already said that the rotations would be in part dependent on matchups with individual opponents.
In my opinion, it would be asinine to start Russell Westbrook mere days after he joined the team.
