In one of my leagues my QB's are Luck and Palmer. Luck is injured and Palmer was horrible week 1. I can pick up Alex Smith or Sam Bradford as free agents today (probably drop Duke Johnson). I'm thinking I keep Palmer 1 more week simply because he's playing the Colts (and I think the Clemson Tigers might beat the Colts <-- kidding).
Anyone have an opinion? My current thinking is that Smith is fools gold. Yes, he killed it week 1 but history shows that he just isn't a high scoring fantasy QB. Bradford (when he's not injured) plays pretty well and the Vikings seem to have put together a decent O-Line for him
