Garcia is great, Collins should be a valuable backup, your RBs look good, your WRs are solid, and I love your sleeper picks in Duckett and Bryant!
Dilger isn't a great TE but Shockey is another pick that could spell trouble for your opponents.
You should consider droping a K and DEF for more sleepers or waiver wire pickups later on.
Overall you have a team that should compete, but you're missing one or two final pieces for the championship puzzle. Hearst and Barber aren't too good for your second RB spot, and your bench is full of sleepers but not all of them awake...
