Salmons for Carter? Augustine or Nelson for Holiday?

[Eazy E]

1) John Salmons is back from injury and has put up pretty good numbers in his first three games back. My least productive SG/SF is Vince Carter and he has been extremely streaky as of late. Make the waiver wire move?

2) A guy in my league just dropped Jrue Holiday. I have a deep PG line-up of Chris Paul, Stephen Curry, Ramon Sessions, Jameer Nelson, and DJ Augustine. Nelson's productivity has been iffy since the Carter/Richardson/Arenas trade and Augustine's numbers took a huge hit when Gerald Wallace came back from injury (thankfully I also have Gerald Wallace on my team). Holiday's numbers aren't spectacular, but he may be more consistent that Augustine or Nelson. Drop either Nelson or Augustine to pick up Holiday?

Thanks.
