Should i trade Steven Jackson for Andre Johnson?

I've got a pretty good team, steven jackson is my #2 back behind maurice jones drew. I've also got marshawn lynch and tim hightower. I've got good receivers but they haven't been able to connect, plagued with injury etc. My WR's are Calvin Johnson, Steve Smith NYG, Percy Harvin, Jerricho Cotchery and i also picked up Malcom Floyd just recently. Good trade for me or not?
