To Be honest I don't really think it's worth it. Not that's it's unfair but you aren't getting that much more for what your giving up. You are already stacked at WR so you don't need D.Jackson and with Vick at QB the targets are going to be split between Maclin and Jackson pretty evenly plus Vick has no problem taking off with the ball, and don't forget LeSean McCoy has been terrific and will continue to get solid touches so I think you can ride what you have through the playoffs pretty successfuly. Your solid at QB. Shiancoe, eh, jury is still out, I would have to see what he does with Jackson at QB, doubt much better than Witten who will be a great option as Kitna realizes that Austin can't seem to hold onto the ball this year. I think Turner is solid but Moreno should pick up the pace and you would prob be better served moving Marshall or Evans for another match up type RB. Plus Moreno has a pretty solid scheudle, he is going to face some weak running D's which will he him get some confidence back and really start to put up some points, i am not saying he will match Turner but would be a solid option. Like i said i would move Marshall and maybe Jacobs to try and get a Green-ellis or Blount. level guy it will only cost you Bench players and you will get some serious bang for your buck into the playoffs with you current WR's.
