I like all of those guys as well if not better than their round two counterparts. Kevin Jones has a great chance to succeed in Martz's offense. Jamal Lewis has a better offense around him, and this is his first year without distractions in a long time. When he hasn't had legal troubles, he's been very good on a PPG basis. If I knew how Deuce was doing I'd say more about Reggie Bush, but if he gets carries, he should be good. Chester Taylor was slow to get started but he should be a solid play, too. And I see no reason to think that Willie Parker will do anything less than last year.
Compare that with guys going ahead of them, like Julius Jones, who has Barber sneaking up on him, and Reuben Droughns who has gotten into a bit of trouble in the offseason. Willis McGahee who scored about the same as Willie Parker, is getting drafted a full round or more ahead of him. In fact, this year reminds me a lot of a couple years ago, when it seemed like the third round running backs all excelled, and the second round running backs, with limited exceptions, busted badly.
Out of all of the guys you mentioned, though, the only ones who don't appear to have to worry about competition for carries are Willie Parker, Kevin Jones, and possibly Jamal Lewis, so if you're looking to go RB WR RB, you might be best off taking one of those two. As we get closer to training camp and have a better idea of who will be starting and what kind of momentum they have, I'd expect guys like Taylor, Bush, as well as Addai/Rhodes, Dillon/Maroney and Foster/Williams to move up these rankings as well.
