Dizik: Dump your second kicker (Gould) and defense (I'd keep Miami). Kickers and defenses are a dime a dozen and hit or miss all year. Play defenses based on matchup (but with Miami, you should be fine all year as they collect turnovers).
Pick up at least one more RB (I'd get two). If there are no starters left as free agents, aim for backups of injury prone players or the second RB in a RBBC (RB by committee). But your two starters are fine and Carnell has some upside. But you need at least one more RB as depth.
Your top three WRs are studs and barring injury, will produce for you all season. Keep an eye on Curtis and Jennings (on your bench, of course) and if they don't seem to produce as the season goes on (and you get near your bye weeks), don't hesitate to drop them for someone who's on a hot streak.
TEs are defined as Gates and the rest. Todd Heap is a solid TE that should get you around 4-6 pts per week. Don't worry about him.
Your only weak spot is at QB and either of the ones you have should last through the season. Check the free agent list for QBs over the next few weeks. If someone has a good game on Sunday, grab one.
For an auto draft lineup, what you have is pretty solid. You are definitely not screwed. I wouldn't even be looking at trades. The only position you could improve would be QB and you'd lose one or more of your good RBs and WRs. You can not afford to lose one of your two RB starters. If you can get someone good for Holt, maybe I'd consider it, but I think you'll have better luck on the free agent list.
EDIT: Wait, I'm in this league. What am I helping you for?
Being right doesn't matter if no one listens.
