if you can grab C.Newton from waiver, make the trade.
the trade itself seems fair
CJ2K have more value than Brady in either auction or snake, despite he is very disappointing on week 1, but Flacco showed good week1 performance.
Brady showed beasty performance, Addai ain't so hot.
trade itself is pretty fair, but if there's Newton on waiver and you got it, then you have Flacco as QB, CJ2K as RB1 + 1 QB that might possibly become next Michael Vick, then you can have Newton as starting QB, Flacco as bench QB and still have 1 elite RB
because if you keep Brady+Newton, it probably won't do you as much good as Flacco/Newton
