I think that you were wise to wait out QB for a while, given the relatively deep second-tier. Better value can be had early taking RBs and WRs, and obviously Andre Johnson and MJD are great. Known commodities, and historically pretty durable.
However I'm a bit concerned about your WR depth. I'd particularly be looking to upgrade at WR, if I were you.
Good luck! please help with mine: viewtopic.php?t=493183
