I don't understand why Chicago would give up James Johnson to land Anthony Parker.
A.Parker is only a marginal upgrade over Keith Bogans and Kyle Korver.
James Johnson over the last two years has been one of the very worst players in the NBA. He's been a huge disappointment in Chicago, and I'm sure they'd be very happy to get out from under the approximately $2 million he is guaranteed next year.
A team taking Johnson off Chicago's hands would be a gift.
I agree that Johnson has been one of the worst players in the NBA last year ... not necessarily this year, he looked a serviceable enough player (not rotation worthy but a solid 12th man type) in his brief playing time earlier this year.
I would happily pay him $2mil a year and continue to give him an opportunity to develop. He is a decent prospect. The cost is minimal compared the potential benefits of Johnson turning into a useful rotation player sometime in the next year or two.

On Johnson, from the brief bit of playing time he got early in the season, I thought his defense was much improved. He was still a train wreck offensively but he was pretty solid in terms of defense and rebounding.
A guy like that is a useful end of bench player. If he can continue to make more progress, improve his D some more and become serviceable offensively - which I think are both achievable targets - Johnson will become a solid rotation worthy player.
