That's not what he's saying at all. For the first have the season lets saying Rodgers has a 96.4 passer rating. Then the second half of the second he have a 96.8 passer rating. He's stayed the same. While Bradford can have 79.2 passer rating the first half and a 79.4 passer rating the last half they both with show as staying the same. He's not staying Bradford is on par with Rodgers just that the graph isn't showing the context of they've been throwing. So blanket statements like the ones in the middle are more consistent isn't completely true
it actually is true and you explained it yourself.
being consistent means staying at/around your average passer rating.
you can stay consistent at 20% or 120%, it means that your passer rating doesnt fluctuate throughout the season.
so in other words, bradford is consistent at sucking ass.
