Opinions on Starting Lineup Please

[riffjaff]

My team has definitely been hit with the injury bug so I need some help figuring out who to start.

QB: Matt Schaub
RB: Thomas Jones
RB: Joseph Addai
RB/WR: Mike Bell
WR: Andre Johnson
WR: Louis Murphy
TE: Antonio Gates
D/ST: Eagles D
K: Jason Elam

Bench
QB: Matt Hasselbeck
RB: LaDanian Tomlinson (Out)
RB: Pierre Thomas (Probable)
WR: Antonio Bryant (Out)
WR: Anthony Gonzalez (Out)
RB: Rashard Mendenhall
D/ST: Dolphins D

As you can see, my #1 and #2 running backs are out and both of my #2 wide receiver options are out as well. The only two places that I'm debating are who to start at QB and which defense to play.

I'm leaning Hasselbeck to start just because Schaub is playing against Tennessee but could use some second opinions on this. As for defenses, I scored 35 points in my league just because of the Eagles D last week, but they're going against Drew Brees and that Saints offense this week. Should I bench the Eagles D and go with the Dolphins D against Peyton and the Colts? Any input would be greatly appreciated.
