So far, I'm going with Rivers over Vick.

Every time Vick has blown up this year, he's been on my bench. I suck at this.
Vick is top 3 in my leagues. Why wouldn't you start him every single week? Last week was his only real stinker.
Personally, it's because I picked up Romo off the waiver wire the week he replaced Bledsoe.I kept starting Vick through week 10, as Romo got progressively better: 15.98 in week 7, 18.6 in week 8, 23.46 in week 9, 25.02 in week 10. At that point, Romo had outscored Vick two weeks in a row, though I had not lost a game by having my higher scoring QB on the bench. I tried to trade Romo but got no takers.In week 11, Romo was home against Indy, and Vick was playing @BAL. I started Romo due to the matchups and the two week trend, and Vick outscored him on my bench. I lost, and would have won had I started Vick.So I went back to Vick the following week, at home against NO, thinking I should have just stuck with him every week, based on the same thinking above (top QB, so why bench him?). Of course, that was Thanksgiving week, when Romo blew up for 41.84 and outscored Vick by 22 points. I lost, and would have won easily had I started Romo.So in week 13, both were on the road. The trend was still 3 out of 4 games to Romo, so I flopped back to Romo, and Vick outscored him by 15 points. Fortunately, Reggie Bush saved me, and I won.In week 14, Vick was @TB and Romo home vs. NO. In retrospect, I'm not sure why I chose Vick, but I did... and Romo outscored him 12.06 to 4.7. Fortunately, I survived it and advanced to the second round of the playoffs.So, entering this week, in the past 6 weeks, Romo had 23.46, 25.02, 5.34, 41.84, 7.28, 12.06 for a total of 115 fantasy points. Vick had 14.52, 15.28, 16.48, 19.96, 22.78, 4.7 for a total of 93.72 fantasy points. Sure, most of the difference in total points came in one game for Romo, but Romo outscored Vick in 4 of those 6 games.So I started Romo this week, and again left points on the bench. This makes the 7th straight week I started the wrong one. And, while I make my own decisions, I do check the FBG rankings every week, and I think they have also missed this particular comparison almost every week. Unfortunately, I may have allowed that to influence me once or twice.Romo still had a solid game this week, and I also have Owens, so I'm hoping to advance to the title game. Next week, Romo is home against Philly, and Vick is home against Carolina. If Vick's groin is a problem, I'll start Romo. If not, I'll probably go with Vick, since he has generally been pretty good at home.I know that's a long post about my team, but I think some others have these two and have to regularly decide, so I thought it might be of interest. And I'd love someone to give me some good advice about how to choose the right QB!
