Who are my best RB's and WR's?

[Booomer]

14 team auction league. ALL TD's 6 points. PPR=1 pt. Kickoff and punt returns are 1 pt every 10 yds. RB, TE and WR 1 pt every 10 yds. Def and special teams, and a kicker.

My team:
QB - Joe Flacco (definitely could upgrade with a trade)
RB1 - Darren Sproles (awesome with KR and PR) vs. WAS
RB2- Fred Jackson @ NYJ
WR1 - Percy Harvin (KR as well) vs. JAC
WR2 - Randall Cobb (KR/PR really ups his value) vs SF
TE - Kellen Winslow
Flex (RB/WR/TE) - Brandon Marshall (WR3_

Bench
RB3 - Jamal Charles vs ATL
WR4 - Marquis Colston vs. WAS
WR -5 Jerem Maclin @ CLE
WR -6 Titus Young
RB 4- Ronnie Bronw
RB 5 - Jonathan Dwyer
QB2 - Nick Foles (Philadelphia's back-up)

K - Robbie Gould
Def - Jacksonville

Who do I start week 1??????

RBS:
1. Sproles - PPR God
2. Chaz
3. FJax - im not as high on his as others
4/5 Brown and Dwyer

WRS:
1. Percy - nudges out Colston because you get KR points
2. Colston - beast slot reciever
3. Marshall - Culter to Marshall!
4. Cobb - normally wouldnt have him this high but you get KR/PR points
5. Maclin
6. Young - nice updside bench stash

Thats how I see em, with there not being nearly as many KR anymore, with moving the ball up for kickoffs, I dont see that playing as huge of a role in rating your players as you might think.
