Normally, i think i would go with KC because they have been pretty strong all year, but OAK is on a hot streak putting up and average of 30 points a game. Also Colts play PHI and colts aint the best verse the run. See the problem? Vick + Run = danger, not to mention he put up good numbers before he was injured. Finally Giants are lookin pretty good this year, and are coming off a bye week well rested, not good for Seahwks.
Bottom line, i think detroit is your best bet.
