I would go Hightower. Even if he does split with Torrain he'll most likely be the red zone man on an offense that seems to be working like a well oiled machine this year. I don't trust Torrain quite yet, and think Hightower is a better skilled back. Thomas has had a bad hammy and he's still a rookie, although I like him as a player and should produce in the future. Not a bad choice just a little riskier. Dallas Clark sucks I wasted a dece pick on him in one of my leagues, he seems to be getting worse and is not worth the risk. Even if Blount doesn't play Earnest Graham isn't a sure thing for a lot of points, look at Redman last week and Ridley who subbed for Woodhead very unsuccessfully.
Yeah that trade is kind of unfortunate, but not killer. I just think Hernandez and Best are just more of touchdown scorers mostly because they're on better teams. Olsen should be fine as a starter.
Hope I helped, here's mine: viewtopic.php?t=503230
