I have the same dilemma but with Rodgers and Big Ben....in our league avg pt per wk (Ben, Brady and Rodgers) almost identical.
I am "going with my gut" really weighing circumstances in favor of Ben this week. Feel that Brady has a tougher matchup (albeit stronger O-line than the sieve that is the Packer's swiss cheese of a front wall) with a better pass rush and physical corners in Seattle. Not to mention the home field advantage of the Seahawks.
I will take some hits for sitting Rodgers, and you may with Brady, but Ben is this weeks answer.
