[Vince, Pt. II]

Ok, my turn for the keeper league I'm in. Keep 6 guys, no penalties or restrictions. Standard lineup with no flex (QB/RB/RB/WR/WR/TE/K/D - 4 pts per passing TD, 0.5 ppr); the only wonky thing is that there is a 4 add/drop maximum for the whole year. We draft a deep bench (12 bench slots), and you're pretty much stuck with them all year. I've got what I feel like are four pretty easy keepers with five options for the last two slots.

QB
Peyton Manning
Colin Kaepernick
Andy Dalton
Michael Vick

RB
Alfred Morris
Fred Jackson
Donald Brown
Andre Brown
Pierre Thomas
Deangelo Williams

WR
Roddy White
Mike Williams
Miles Austin
Titus Young

TE
Vernon Davis
Greg Olsen

K
Rian Lindell

D
San Francisco
Seattle

I'm thinking the easy keepers:
QB Manning
QB Kaepernick
RB Morris
WR White

And here are pretty much my only other options:
WR Austin
WR Williams
TE Davis
D SF
D SEA

I'd really like to package Manning with one of Austin/Williams for an RB, but I'm getting no love from my fellow managers (I'm the only 49er fan in the league and no one is very high on Kaepernick, so no taking advantage of the Kaepernick hype). Running on the assumption that I'm not able to make a move before locking in my keepers, what to do with the last two slots? Davis is intriguing because with Crabtree out (and Boldin to keep defenses honest) he should see a huge workload. Seattle and SF are arguably the two best defenses in the league, and while Austin and Williams are nice, neither are consistent enough to be top tier. Then again, either of them are good enough that they could take that next step this year. Decisions, decisions.
