solid team, I don't think you have a lot to worry about however in an 8 person league a lot of talent can end up getting stacked in one team. Can you post the other 7 teams?
You're WR crew is good and has some depth...I like your RB's too...very Questionable on your QB's. Peyton is obviously a good pickup when he comes back but I'm not sold on Eli as a starter.
I know it's textbook but I'm not the biggest fan of Mendenhall at 7th...I I'd be interested to see the whole draft result set, but I personally would rather have got A Rodge, or Andre Johnson and then a Lesean mccoy or maybe even mendenhall on the way back through. It's all personal preference though.
Your bench has good depth and as long as you didnt get yourself in BYE troubles you did good work.
Don't be so hard on yourself, I think you drafted an A-/B+ team
(sorry for no comments on defensive picks, I never play defensive leagues)
