1. Foster (Would not argue WR here but RBs generally more scarce.
2. Calvin
3. Marshall
4. AJ Green
5. Andre Johnson/Peterson/Rice (just pull one from a hat).
In general, my list is compiled to reflect the players that look the safest week in, week out, AND have history of consistency. Peterson is SO awesome but he's also in the midst of a record season and NO RB has ever broken 2000 and backed it up with a pick justifying top 5 in the league...nobody. So its more a reflection of preference of a safe top talent vs. the guy that is obviously capable of doing so much but, let's face it, is kinda like everyone's little darling. We love to love Peterson but history says it won't repeat.
The other two guys I would be tempted to put in the 5 spot is Dez and D. Thomas but didn't based on the lack of "proven history", although I think BOTH will do better than guys like Cruz and Julio (who were absically consensus top 3 guys just 4 months ago. Things change fast with unproven guys so I'm going with the guys with history.
