This is a pretty tough one but I think, based on the value picks you got, that Mock 12 slightly edges out Mock 11. And here's why:
Although you have reeeally good depth in WR with #11, that RB situation just leaves me worried at the end of the day considering you have no one else to take that spot after Richardson. What if MJD and Mathews both flop this season?? Unless you can pull off a nice looking trade, then ur screwed! If u can trade some of your WR depth for a good back up RB like Fred Jackson, then I'd take #11.
I do like how you got Cam with ur 3rd/4th picks cause that's the perfect spot to get someone like him. I also think CJ2K will come back with a vengeance this year (top5 RB for sure), and you got Fitz. While I'm a little uneasy about Vereen or Greene, you have solid depth in each position. The only thing I would've done is take a WR with ur last pick (or better yet instead of Ravens def, then play matchups the whole season). Got high hopes for Cutler, besides I don't think there's any real reason to take 3 QBs in a draft. WR position is deep this year, that's why I would wanna shore up RB before anything. But with that said, I really like your WR depth in #11 haha. MJD is just too risky in my book =/
