Please some advice for who to play week 4

[FavreKilledMe]

This is my first league, have always knocked it in the past, but starting to love it now. I'm 1-2 and need to start making up some ground as I play a 3-0 this week 4. Any suggestions on who I should start would be a huge help; also any ideas on guys to drop and some sleepers to pick up.

If you can't see it, Here's the lineup I have set so far:

Starting:

Mark Sanchez, QB @Buf
Frank Gore, RB @ATL
Rashard Mendenhall, RB BAl
Jeremy Maclin, WR WAS
Randy Moss, WR @MIA
DeSean Jackson, WR WAS
Tony Gonzalez, TE SF
Ray Lewis, LB @PIT
Seahawks D/ST @STL
Nate Kaeding, K ARI

Bench:

Brett Favre (bye, should I drop this chump?)
Steve Smith, WR CHI
Kevin Walter, WR @OAK
BenJarvus Green-Ellis, RB (Heard he might clean up this week, but who to replace?) @MIA
Louis Murphy, WR HOU
Johnny Knox, WR @NYG
Jets D/ST @BUF

Any help would be huge guys. I appreciate it in advance.[url][/url]

The only change I might make for this week would be putting BJGE in for Maclin at the RB/WR spot. RBs are almost always better there because they are most consistent, but it is a Patriot RB we are talking about so that evens things out pretty much.

How many teams in the league? Who is available on the WW? I am not sure I would drop Favre yet, unless there is someone good out there, but the leach would be pretty short. Otherwise your squad looks pretty solid.
