Who should I start for my fantasy football team?

I have just a little league between my roommates and I have been going back and forth on what I should do for my team.

First thing to know is that there are only 8 teams so good players are loaded up in every roster.

My team:

QBs : Matt Schaub, Phillip Rivers

RBs : Adrian Peterson, Michael Turner, C.J. Spiller, Beanie Wells (not by choice, didnt select fast enough)

WRs : Randy Moss, Roddy White, Malcom Floyd, Terrell Owens, Jeremy Maclin, Steve Breaston

TEs : Vernon Davis, Kellen Winslow

K: Mason Crosby

DEF: Baltimore

I am having a hard time trying to decide on my starting QB, my flex W/R position, and Beanie Wells/C.J. Spiller.

I know Vincent Jackson is gone but I also know that the Chargers have one of the easiest schedules in the league with other excellent options...hence my selection of Floyd for he will be the #1 receiver most likely behind Gates.

However, I cant help but love the Schaub, Johnson connection. Also Schaub is looking to another great option at RB this year to help out.

Comments?

now for Wells and Spiller.

I didnt want Wells at all because I know how well Hightower has been playing this preseason and i was going to select another player...but oh well.

Spiller I was selecting because he is a great talent that should be starting for the terrible team of Buffalo but i think that Taylor is going to take the job for the entire season if he stays healthy.

My big question here is whether I should drop one of these two and pick up Jerome Harrison...who isnt necessarily as talented as them but has the starting position at a slightly revamped Browns team.

Suggestions?
