Taking away QB's, or calling it a wash, is it that crazy to say Seattle could be a better TEAM.
RB- Lynch > Gore, depth-wise, Seattle has Turbin and drafted a RB Christine Michael.
WR- Tate/Rice/Harvin/Baldwin > Boldin/Patton/Jenkins/Williams/Manningham
TE- Edge to SF b/c Davis is a monster.
OL- Slight edge to SF as a unit but Seattle's is really good.
I would give the DL edge to Sea, and LB's to SF, but Seattle's LB core is pretty underrated. Hard to compare though since Sea is a 4-3, and SF runs a 3-4 scheme.
Big edge in the secondary to Seattle, those dudes are absolute monsters, add in Winfield just makes it insanely good.
Don't care too much about FB.
