My qualification for a solid 2008 fantasy RB would have to coincide with the better OL and QB that can throw the ball,
Ladanian Tomlinson sure meets that prerequisit but injuries to Phillip Rivers (ACL), Tomlinson (Knee) Antonio Gates (Toe) has to play a heavy problem for the Chargers. If all is clear then yes he will regain the rushing crown once again.
Steven Jackson is a very good RB but questions with the OL and passing attack has to come into question since double teaming Torry Holt will be a must and 8 in the box will be an everyday occurence. So I can not put allot of emphasis on him
Joseph Addai is another great draft pick for the Colts but teams in the AFC South has already worked there defense to defend the pass and run so Addai's stats will come down in coming months. The acquisition of Mike Hart will add the needed 1-2 punch that the Colts need but intern decrease the amount of carries that Addai gets each game.
Andrian Peterson is another outstanding draft pick for the Vikings that with Chester Taylor has increased the value of the run game and help the passing game that much better. This year Tavaris Jackson will need to put it all together or his time at the helm will be limited with the acquisition of John David Booty that will be on the sidelines waiting his turn.
Maurice Jones-Drew should recieve some attention with the Jaguar Run game ranked #2 in the NFL last year and this is probably the last year for Fred Taylor since he is wanting to break Browns RB Jim Brown #8 all time rushing record befor ecalling it quits. Taylor needs 1600 yrds to do it and playing the AFC and NFC North will get him extra yards that would not normally be there.
Marshawn Lynch is the other candidate that should get some consideration since the emergence of the Bills Offense and Defense restructure and the 2nd year starter Trent Edwards will need the push of the run game to keep the hopes alive for the AFC East crown or a wild card invitation.
Rookies of consideration is Jonathan Stewart, Rashard Mendenhall and Felix Jones due to the system that they are drafted to and the type of offensive power the teams protray.
I have not mentioned Darren McFadden since the Oakland Raiders are behind the 8-ball with how they are going to use him. HIs running style is a homerun style each time he gets the ball but the OL is questionable and with no real Passing game the running game will be questionable to the amount of yardage can be acquired.
