I think you are confusing rumored or speculated with reported.
But I agree, we may well not bring in a guard better than Tyler Johnson. But Tyler Johnson is much better than the trio of PGs that we had early last season, the only hitch being his ability to stay healthy.
We all know your feelings on Tyler but this team played much better when he was in the lineup (and when he and Kelly were in the lineup). It was a very small sample and our opponents had no need to do any serious scouting but it's not like Tyler or Oubre were new to the league. Of course, at this time we don't even know if Kelly is coming back.
