Deep RB for Week1 Flex

[MTUCache]

Plenty of options, none of them particularly appealing right now...

Starting 2 RB, 2 WR, 1 RB/WR.

Roster RBs:
Stephen Jackson (STL) - Lock for #1RB
Reggie Bush (NO) - Lock for #2RB
Willis McGahee (BAL) - Possible Redzone Carries
Jamal Lewis (CLE) - Aging, horrible pre-season
Jerome Harrison (CLE) - Failed handcuff, WW-bound
Fred Taylor (NEP) - No news can't be good news
Chris Brown (HOU) - Again, little to no info here

Roster WRs:
Marques Colston (NO) - Lock for #1WR
Deion Branch (SEA) - Not even a given on the roster as #3 reciever.
Chris Henry (CIN) - Lots of upside. Lots of downside.

In short, I gambled big-time in the draft in the middle/late rounds on a lot of chaff RBs, hoping that by Week 5 or 6 I'd end up with a bunch of starters (after rookies didn't pan out and guys ahead got hurt). I've got bright spots at QB/TE (PManning/TGonzalez), but the rest of my team is mid-tier at best. Right now it looks bleak. Real bad in fact. So I'm hoping just to keep my head above water in the Flex spot for the first few weeks until something breaks.

I pretty much have to go with Colston/Henry as my WRs, right?
Do I start McGahee here and hope he steals a goal-line TD?
Is there anything about Taylor or Lewis that are looking positive right now?
