Vick. Easy decision for me. Kelly's offense is perfect for him and as long as he stays healthy, he will be one of the best overall fantasy players and should be started every week. Plus Wilson is playing against the Niners.
I had pretty much the same problem this week with Vick and Kaep as my other quarterback. Ended up going with Vick as I just see a low scoring game in Seattle plus Kaep is the away quarterback so crowd will make life tough for him and the offense.
I actually had Vick as my back up in almost every league that I play in and the only one he isn't starting in this week is the one that I have Peyton as the starter. I actually am starting him over Tom Brady (which looks like a good decision after what I saw last night from him). Vick healthy in this offense looks like a winning formula. Now thankfully he was my back up quarterback as I don't expect him to make it past week 8 with this offense and how many hits he takes. Might as well ride him as long as I can.
