Oh, and in the interest of full disclosure... I am NOT playing web as of now, but I think my options are a bit different from yours.
I have two slots where I could play him. In place of Woodhead, or in place of Fred Jackson. Also, in order to have a comfortable margin of victory, I only need to average 10 points from those two slots. I think Jackson and Woodhead are both safer bets. I am playing conservative here because I don't really need outsized numbers from these slots. This may change if Kitna boffs the pooch on Saturday. At that point I could pull Woodhead or Jackson if I thought I needed to take the risk for more potential points. (for ref, Webb put up 13.56 last week in my league).
I thought about picking up Tebow and playing him instead of Kitna... But too risky IMO. Kitna is my conservative bet. (I am playing him over Aaron Rodgers right now.)
Also, I am from houston so that may unfavorably bias me toward Tebow, because I am overly pessimistic about houston. <grin>
All that said.. I like Tebow for this week.
My final game is not until week 17 so I have already picked up David Garrard (playing houston in week 17). IMO that's 30+ points right there. But we will have to see what happens to Rogers this week.
