For the analytically challenged among us, the chart is sorted based on the differential between a player's passer rating when not under pressure and his passer rating when under pressure.

That doesn't answer my question but you can still use it. The darker the green in the second to last column, the better the player is under pressure.

Passer rating under pressure looks exactly as you'd expect it would:

1) Aaron Rodgers 105.0
2) Russell Wilson 103.0
3) Tyrod Taylor 99.4
4) Tom Brady 99.0
5) Ben Roethlisberger 97.4

Gotta go a long way down to find Alex Smith, with a rating of 77.6, and Cousins with 82.7.

But the key to keep in mind is PFF still uses passer rating, instead of ESPN's proprietary QBR. QBR takes into account yards gained on the ground and whether they converted to first downs or not. These passer rating stats do not.

As we know, Smith is among the league leaders in those stats. So this data from PFF should be interpreted as rating when the QB throws the ball while under pressure.

If you take into account first downs gained via scramble, Alex Smith would vault up the list.
