Is this a realistic trade?

[Spoon_03]

I've started a nuggets dynasty and i made a couple of trades here it goes...
Carmelo Anthony and Yakhouba Diawara for Joe Johnson. I added Diawara because of salary differences between joe and melo. I also traded Kenyon Martin, Anthony Carter and Bobby Jones to the Wizards for Antawn Jamison. Is this trades realistic? IMO the Johnson-Anthony trade is pretty good and also my acquisition of Jamison is good also because in real life their big three in washington doesnt work out this past years. What do you think guys?
