I'm normally not in favor of trading guys who are top 5 players at their position, but you have some real injury questions at RB. If Murray and Richardson were healthy I'd lean against doing this.
But you get a premier RB who has never been hurt plus an upgrade at TE.
The rest of the players are negligible IMO and I would leave them out of your mind.
I think I would do this.
And I'd get rid of Cruz, not Green. Nicks hasn't been healthy this year and I think that could hurt Cruz's value just a little bit now that Nicks is getting back to being 100%.
I could really use an expert opinion myself here:http://www.fantasyfootballcafe.com/forums/viewtopic.php?t=527588
