I think Tari starts after KD retires in 2 years and when KD misses games. In the meantime he’s gotta try to get through a season healthy enough. He’s injury prone unfortunately, hopefully that can improve somehow, but it’s definitely a concern.
I can predict what it SHOULD be, but Ime is an idiot when it comes to rotations and lineups, so there's no telling what he actually does. It could be Capela, Tate, Davison, Green, Crawford for all we know.
DFS has laced up before. Just not with the Rockets. I don't think he will start by the end of the season as I think inertia keeps JSJ in the starting lineup, but I do think the Reed, Amen, DFS, Durant, and Sengun lineup will be a very strong lineup if they are all healthy. I think the Rockets need a 2nd POA defender with Amen starting, whether that be Okogie or DFS.
