i do find it funny to see people say "when will they get erron rodgers help on defense!" but a big part of the reason they CAN'T is because of how much of the cap he is eating up. it's something that will come due for the niners, seahawks, panthers and other teams as well. you just can't afford all these guys AND pay a qb $15-20 mil a year.
in the niners case we will probably be stripped pretty badly. kap, crabtree, aldon, iupati contracts all coming due. we could MAYBE keep 2 of them. and that's to speak nothing of bruce miller, boldin, whitner and culliver (who we will need because rogers and brown will be gone for sure)
