Here are my early tiers:ITomlinsonPetersonS. JacksonIIWestbrookBarber IIIGoreAddaiIIIPortisLynchGrantJones-DrewBushIVMaroney LewisR Brown Of the guys who are listed on some others, but I can't have higher at this point:LJ-- here was Jamal Anderson's 2000 season: 282 rushes, 1024 rush yds, 42 rec, 382 rec yds, 6 TD's. 11.0 FP/G. Both were coming back on bad teams. LJ's injury (foot) actually concerns me more than Anderson's knee would at his size and age. That's about his upside in my opinion.Parker-- coming off the injury, he'll be 28, which puts him just on the wrong side of the age curve. Okay for a star back with no recent injury history, not as good for a solid back with a broken leg at the end of the season. 2 TD's. He is imminently replaceable at this point in his career. The question of course, is by whom.McGahee-- a rush attempt compiler with a career 3.9 ypc, on an unsettled offense, that gets to play against the NFC E/AFC S this year instead of NFC W/AFC E. He had 2 games of 29+ attempts in his last 4 (and was the only back to do so), so I think he carries a little extra injury risk into the season. The combination of all those factors means he is borderline top 15 for me at this point.
