Which rookie will have the most impact in 2008?

Malcolm Kelly will be an immediate red zone threat and score some TD's. Has good hands and would seemingly work well as the X in three receiver sets. He'll hopefully make some big plays catching a few touchdowns and hauling in first downs, if not stretching the field. Devin Thomas has more physical upside, but my feeling (and that's all it is since I've not watched either play much at all) is that he's more raw than Kelly (two years of DI football, only one as a starter v. 3 years of top DI experience) and will take a little longer to develop. With his athleticism he might also work well as a Z eventually taking over for Santana - though I'm basing some of this off the Gibbs/Saunders/Coryell offense since I am not all that familiar with the Zorn/Holmgren/Walsh tree.
