Another great point. The most important impact he had on the film is the transferring of information to the audience that Jyn was abandoned by him because people we’re starting to piece together who she really was. Other than that and the “Save The Rebellion…Save the dream” line he is completely useless just like Lor San Tekka in TFA.
Except Saw is made out to be a very important character in the film. Tekka is just an old ally with the map who sets thing in action at the start - no need to be anything more.
They both could have been much much more. I expected much more out of them. That’s the point of the comparison.
You can say in Lor San Tekka’s case it’s due to Max Von Sydow being in the film but still…
