To run Lucasfilm and John Knoll was a Lucasfilm employee who wrote the R1 story treatment during ROTS that he was going to pitch to George eventually. Dave had a Mandalorian story treatment. Just to clarify those missing parts.
It confuses me to this day why George chose KK over Rick McCollum. We could have gotten George’s sequels, underworld & better versions of Kenobi & BOBF. Rogue One and the Mandalorian would’ve still came out bc Knoll & Filoni already made story treatments
