Seems like you'll have to take some gambles, via trades and the WW. I'd be paying close attention to injuries and try to beat others to the wire. Other that that, I would print out the round by round draft results and see what went wrong.
Did I reach for sleepers too early?
Did I wait too long on a thin position?
Did I fall in love with certain guys?
You should get a clear picture of what went wrong on draft day. Looking at your roster, after Pujols/Sizemore/Rios, I can't figure out who your 4th pick was.
You have your work cut out for you, but this season can be a valuable learning tool. Manage to the best of your ability.
Best of Luck.
P.S. All this goes out the window if you tell me it was a 16 team league.
