Don't let them bring you down. Lot's of irrationally mean people on these boards. But you can't go around provoking people and expect them not to swing back. A lot of times, these guys are heavily invested in a certain player (Rashaad Penny, Royce Freeman) that they begin to get irrational.
In regards to Penny, I don't get it. I liked his talent but Seattle hasn't exactly had a great track record with Runningbacks, in fact, it's looked more like a revolving door. Chris Carson looks really, really good. Looking like a nice buy-low for dynasty owners. Not sure what to even do next year, but he can safely be dropped in redraft formats.
