In addition to that, despite the pool of starting QB's being larger, you have to start fewer QB's in the league.
There is a pool of 32 starting QB's for 12 starting FF positions.
There is a pool of 20ish starting RB's for 24-36 (depending on whether you start only 2 or can start 3) starting FF positions.
So, there are fewer starting RB's that don't share carries in the NFL then there are starting spots that need to be filled in FF, while there are nearly 3 times as many starting QB's in the NFL than there are starting spots that need to be filled in FF (this is all assuming a 12 team league).
That, combined with what Vhawk said about how there is generally less variation from top QB's to mid-late QB's than there is from top RB's to mid-late RB's (of course as has also been said, this year has been a bit of an outlier in this manner due to Manning's record-setting year, but generally it works out as described above).
