I'm actually in the same boat in one of my leagues. I chose to start Tolbert and here's why. With the Cowboys O-line as young as it is I see Jones having to stay in on pass protection so I feel his PPR is very limited this week. I feel the same for Witten but feel he has a MUCH greater chance of catching balls against an aggressive Jets D that was vulnerable in the middle of the field last year.
Tolbert has a decent match-up with the Vikings this week especially since Kevin Williams is out. Goal line carries are gonna be huge in that game. It doesn't hurt that he's great catching the ball as well and could see the majority of 3rd down plays.
Would love to get your opinion on my thread! viewtopic.php?f=19&t=495495
