MORE NUMBERS FOR GOOD MEASURE

Strength of schedule, point differential can be used to explain Bears’ success

According to ESPN’s total QBR — which “incorporates all of a quarterback’s contributions to winning, including how he impacts the game on passes, rushes, turnovers and penalties” — Trubisky is the NFL’s fourth-best quarterback with a 75.1 mark. Trubisky only trails Drew Brees (86.2), Patrick Mahomes (83.6) and Philip Rivers (75.4) in that system.

PFF, which grades every play and throw, doesn’t see the same things, though.

In PFF’s most recent rankings, Trubisky is rated as its 28th-best passer. He has the highest percentage of negatively graded throws (23.8 percent) of any starting quarterback. According to PFF, each throw has varying positive and negative degrees that it can be graded on. Trubisky’s rushing grade, though, does lead all quarterbacks.

Trubisky’s ratings certainly stand out when compared to Jay Cutler’s Bears run. It’s early, but they’re not even in the same conversation. Cutler’s best passer rating was 92.3 in 2015. His best total QBR was 70.9 in 2013.
