All these RB's will see timeshare.
Julius Jones comes into Seattle untested. He LOST his starting job to Marion Barber in Dallas. Jones may be an upgrade from last years Shaun Alexander, but he's not much better. Jones can still lose his job to T.J. Duckett. Duckett is also a former 1st round pick and can bang out the tough yards that Jones can't (i.e. goal line situations). also, Seattle's run game hasn't been the same since Steve Hutchinson left for Minnesota. That's where Alexander's decline started, then snowballed downhill from there.
Rudi Johnson was dinged up last year. Even when he wasn't hurt, his play was average. His offensive line didn't help. The Bengals have issues on the offense as a whole. We don't know if the lineman will stay healthy (3 starters out last year). Also, Chad Johnson and T.J. Houshmanzadeh aren't happy so who knows what's going to happen here. Team chemistry is not the greatest with the Bengals this year. Johnson will turn 29 and his play is already declining. Johnson has always been a workhorse back instead of a playmaker.
Ronnie Brown is your guy. He was the #1 fantasy RB last year before he was injured. He did that WITHOUT a big name QB. They will have their struggles on offense as well. But RB play was not affected last year when they were rotating QB's on a weaker O-line. Ricky Williams will eat into the time share but as the season goes on, Brown should get stronger (barring injury, but this could happen to anyone). True, Brown is coming off a nasty knee injury from last year. He may not start strong but should finish strong, when you need him for fantasy playoffs. Ronnie Brown is also younger. Given the opportunity to choose a franchise RB, I would put my money on Brown. Ronnie Brown has way more upside potential than Jones and Johnson. Depending how you draft, you coudl keep Brown for 2010, 2011, 2012.
