You went in to the draft with 4 great keepers and you drafted well.
I agree with the order of players you targeting in your draft. Knowing that you had two backs, 1 quarterback, and 1 wide receiver, snagging the top tight end was a good move. Brandon Lloyd should regress some but he gets to have Kyle Orton throwing to him just like last year, so he'll retain some value. Reggie Bush is a flex play in PPR leagues, especially if he can keep the lead back role. It seems Bush won't be returning kicks in Miami (Davone Bess will keep that duty) so he loses a little value there but all in all a decent upside play.
I agree that you probably went for your backup a bit early, but you got decent value throughout the rest of the draft. Sam Bradford should be able to take a step forward with Josh McDaniels as his offensive coordinator, so if Romo falters he'll be able to produce in his place. If all else fails, he could have decent value as a trade chip if you need to patch up somewhere else. The Ben Tate pick looks as important as ever now with questions about Arian Foster's health. I don't think the hamstring is a huge concern, but better safe than sorry.
All in all, your team looks like it should be competitive. It doesn't hurt when you have such a good keeper class. Good luck
