I have been real high on Portis this season, I have had him as my RB1 all pre-season, but he has really turned into the ultimate high risk/high reward player.I can't help but think that Portis will be at 80%-90% for much of the first month of the season, and that Betts will get the majority of goalline carries during that span. If that's true and Betts proves to be effective at the goalline, I can't imagine Portis getting the ball inside the ball with a bad shoulder for the rest of the season.Another area of concern: how much can his shoulder improve during the season? I mean after he get's tackled I can't imagine that his shoulder will get much better. He's really one tackle away from missing the entire season. I know that every player is "one play away", but the odds for Portis missing time have been greatly increased.As big of a fan as I have been of Portis (and I sit in the 4 spot), I really don't think that he's worth the selection. Call it personal preference, but I keep recalling the old saying "You can't win your fantasy league with your first round pick, but you can sure lose it".Now if you are sitting in the 4 spot and you welcome the risk/reward so be it, but for me I have to think with my head and not my heart and for me that means that Barber is my choice this season at the 4 spot.
