Roster spot available and what to with WR

[vman56]

First, i have a roster spot available for RB. Scoring is 1Pt per 10 yards rushing and 1PT per 10 yards receiving. ALso, 8pts for a TD. We are a small league so on the WW is the following...

Jones, Thomas RB NYJ
Julius Jones RB SEA
Larry Johnson RB KC

who is the more dominant pickup???

ALso, do you beleive it is too soon to dump Braylon Edwards? I can get...

Devery Henderson NO
Devin Hester CHI
Nate Burleson SEA
Donnie Avery STL
I am leaning to Henderson given the air it out offense in NO.
thanks,
