League is PPR, with IDP. You're allowed 5 keepers with no penalties. However, you can only keep one player per position. I'm bolding players I'm pretty sure I'm keeping, but I do have a few questions.
QB: Roethlisberger, Rivers
WR: Reggie Wayne, Pierre Garcon, Jordy Nelson, Jeremy Maclin
RB: Maurice Jones-Drew, Demarco Murray, Joique Bell, Jalen Parmele, Jonathan Dwyer
TE: Jason Witten
K: Jason Hanson (Det)
Def: Minnesota, Pittsburgh
LB: Derrick Johnson, Kevin Burnett, Chad Greenway
DB: Kam Chancellor, Janoris Jenkins
I'm not entirely sure on keeping Reggie Wayne, but he was the most consistent of all my receivers this year, and it wouldn't hurt to have him back.
At RB, I'm really torn between MJD and Murray. MJD has a huge record behind him, but he was hurt this year. No clue if he returns to form (though I'm thinking he will). Murray was better this year, but MJD is so much more consistent (when healthy) than Murray was this year. The rest are just low-end fodder, and aren't a concern to me.
For my 5th keeper, I'm torn between keeping PGH Def, which is usually very highly regarded, and will likely have a bounce-back year, or one of my LBs (most likely Greenway).
