This was interesting for me.
"We've actually upgraded some positions."
So, he says "positions", more than one. Can't be shooting guard, because no way is Henderson as good as Wesley (unless olshey was sure Wes would be diminished physically). Can't be power forward. So that leaves center and small forward. So I guess he shared the opinion of a lot of posters that Batum wasn't that valuable anymore, he is basically saying Aminu is better than Batum. And also he may have felt Lopez was good but not really 10-12 million dollars good, and that Davis and Plumlee will be better.
Also saw he was quoted as saying "I hope so" when asked if he would make a trade before the season. And he specifically said backup PG and SF were the positions of need.
