Should i make this trade? fantasy basketball?

i'm torn on this trade, it feels a lil two step forward, two step back but i'm intrigued just enough to at least examine it. i have been offered garnett and maggette for okafor and danny granger. for wing players besides granger i have brandon roy, rudy gay, francisco garcia and james posey, for post i have tyson chandler ilgauskas jason maxiell. my guards rebound well so im not worried about the slight drop in boards between kg and okafor. any ideas?
