I would go Westbrook and Jackson. AP looks like he is going to play for sure. I wouldn't use Gerhart.
Westbrook can be solid, I think, on a week by week basis. Its the longevity that is the issue. I think he is definitely a better play than Gerhart this week.
And, I too would pick Ocho at WR.viewtopic.php?f=19&t=487389
