I would go with Shockey (who IS INDEED "hot" after his 100+yd performance last week btw) who plays a divisional opponent, while Witten is only having an "average" year by his own standards, thanks to the emergence of Miles Austin as Romo's new favorite and most productive target.
*Big $$$ 12 tm, H2H Hyper-performance/Milestone keeper league:
QB-RB-RB-WR-WR-WR-TE-K-D/ST + several other options
*AP,*Bradshaw, Fargas, Chester T.
*R.White,*B.Marshall,*Austin, Mason, Manningham, Holt
*MINN D/ST, SEA D/ST---(for wk 9 only vs DET!)
(4-3, 2nd in overall points)
