Fantasy Football Help!?

I love the lineup but your WR set is debatable. Wes Qwlker has Brady throwing and he is almost guarenteed a TD even against Indy, promblem is who should you take out. This may sound really dumb but I had a similar decision. I took out "Ocho-Cinco" because he's getting yardage but TJ is stealing alot of TDs and yardage away from johnson. Keep the RB and put Welker in.
