I'd say for a 12 man you did really well. AP is probably a safe a bet as you have in fantasy. I like WRs like Vincent and DeSean Jackson because all it takes is 1 big catch in a game and boom, you have like 12 points, and they deliver on that more often than not. I'm hoping Hightower has a good year (he's on my team, too). With your QBs and Defense, I'd say you could probably play the match-ups and come out fairly well. And what's not to like about Danny Woodhead? Had him on my team last year and he provides a surprising number of points, though last year he could play both WR and RB for some reason, so that really helped.
I'd give you an A, but fantasy is so random, all the preparation in the world can't beat that lucky SOB.
