At what point in the season do you decide to trade your "studs"? If you were a Romo, Brady, or Favre (and to a lesser degree, Moss) owner, would you trade these guys away at this point to solidify a more secure starter in the playoffs? By secure, I obviously mean a guy who is going to play. Every year teams lock up playoff spots and/or home field advantage, then inevitibly sit their starters, destroying many fantasy owners hopes of winning it all. So, is it a sound strategy to trade these guys for a guy who will assuredly start? How might this change in a keeper or dynasty scenario?
