I don't have nearly the options available to me that you do, as my pool started in Week 1. (Or maybe you just picked some REAL garbage teams and got this far, which is good if you could do it!!).
Teams I have used: Oak, SD, Atl, Phil, Ind, TB, GB, Buff, Pitt, Tenn, StL.
Anyways, I do have some of the teams available that you do....and I have settled on New England. I think I'd be taking them even if I had not used those teams listed above. Minnesota has played some AWFUL road games...they don't seem to be into the game at all once they leave home. Winless away, and aside from Week 1, their smallest margin of defeat on the road is 13 points. And with the Pats in the division race hunt and off a tough loss...I like 'em.
The other team I was considering: New Orleans - I originally had the Saints penciled in for this week, but again, looking ahead, I see that there are some tough weeks coming, and the Saints have quite a few easier opponents left, so I think it's adviseable to save them if you can. Depending on how many teams you've already burned, having the Saints available may bail you out somewhere along the line the way it lines up. Look at the schedule and you'll see they are a pretty good pick for Weeks 15, 16 or 17.
I also don't like the idea of ever taking a road team unless it is absolutely necessary.
Good luck.
