It looks like Gibson is not (and probably never was) part of any offer for Rudy (per Mark Stein ESPN.com):
http://espn.go.com/blog/truehoop/post/_/id/18798/what-next-for-t-mac"In one of its proposals to Portland, sources said, Chicago has offered to absorb Fernandez's modest $1.25 million salary for next season with cap space in exchange for a future first-round pick.
Sources say Portland, however, has believed that it can do better in a Fernandez deal and is holding out for more, even though New York also balked at the Blazers' demands this week and elected to sign Roger Mason to a bargain one-year deal at the veteran minimum of $1.4 million.
It’s widely assumed that the Blazers want Taj Gibson back from the Bulls,
but sources say Chicago is not about to include Gibson in Fernandez talks. James Johnson is the best young player Chicago has made available.
The Oregonian reported last week that the Knicks and Celtics were the other teams, besides Chicago, chasing Fernandez hardest, but we’ll have to see how choosy Portland intends to be from here. "
Like I said earlier, the report that Gibson was offered was likely BS. The blazers would have already made the deal if it were true.
