Hey I agree with your RB's being PPR gold, although I'm worried about total yardage from them since they only score for every 20 yards. I think Stafford is outstanding in a league where TD tosses count for 6. I like Owen Daniels as far as TE's outside of the big 2 or 3 go. My only real advice here would be to lose Jahvid Best and see if you can grab some other sleeper type, preferably a RB. Best is on PUP and could very well miss the entire season. I've even heard reports that his career might be over, (of course) I hope that isn't true.
