Was this a good trade?:?

i traded t.o, trent edwards(my qb is brees) and nick folk(i have crsoby). for fred jackson, my only good rb was barber but it looks like he will be hurt, so im putting in felix jones and i have plenty of good recivers, t.o was not putting up number compard to my other recivers. im 2-0 right now and fred jackson highly increase my chances of winning the next 2 games. do you think he will put up points once he is second string?
