This is an interesting matchup.
I have Warner on my fantasy team. My wife is a Packers fan. I'll probably be sleeping on the couch when all is said and done.
Anyways, I imagine GB will come out gunning at the start hoping to take advantage of St. Louis being a little rusty after a bye week and getting a quick score.
Remember, Warner leads with total interceptions and he does have an occassional 2-3 interception game which would definitely hurt.
I also wonder about his voice, and whether if GB will try to capitalize on that by trying to force him to call audibles.
I'd have to give it to the Rams though.
