Well, it's pretty much a points-only league, so it comes down to always having players who are producing in that department. You might want to consider paying really close attention to streaks each day and picking up FAs as they start to get hot, and drop them when they're starting to cool off. Basic advice, I know, but it's valid.
You might still be able to find some value for Iginla. If you can get someone who is producing at a better clip than he is, then go for it.
Your goaltending, however, is your biggest obstacle. Since there are SIX goaltending categories, you're going to need at least one more goalie to fill out some of those stats. Drop a player like Bolland for the best goalie still available on your FA list...or maybe try to trade Iginla for another starter.
