Fields used to have a bunch of these games, now his worst games are not as terrible as they used to be. That tells me his floor is rising, which is promising. Here are the 10 worst QBR games this season, so far. 

10 Worst Games (QBR)

Mac Jones - 7.0
Jordan Love - 7.8
Aidan O'Connell - 8.3
Daniel Jones - 8.6
Desmond Ridder - 9.2
Joshua Dobbs - 9.4
Russell Wilson - 10.1
Lamar Jackson - 12.3
Jordan Love - 13.0
Ryan Tannehill - 13.3

Fields has 3 games between the 23rd and 32nd worst (ironically, his first 3 games), but no longer any in the bottom 20.  

Funny to see Jordan Love on their twice, and the difference for him compared to Fields is his last two games have been the terrible ones. Normally it is understandable that an offense or QB struggles in the first few weeks, due to the lack of game reps from the preseason. 

In Fields' 3 bad games, he had 3 TDs and 4 INTs. In Love's 2 terrible games, he has 1 TD and 5 INT. So you can see the floor difference there too.

If you want to talk ceiling, they both have 2 games over 70 QBR, Fields had 8 TD and 1 INT in those 2 games, and Love had 6 TD and 0 INT. So their ceilings are pretty comparable at this time.

 

The Bears seemed to have dodged two bullets, one, by not selecting Mac Jones. The other, not trading for Wussell Rilson, he has been so bad, I purposely spelled his name wrong. If he didn't have garbage time stats, he would have no stats. He had like 39 yards passing until the last drive of the game, and he also got a TD. Before that drive, he had the lowest QBR game in the last few years.
 

Another interesting nugget, Jordan Love has been the benefactor of 5 DPI calls for a whopping 163 yards. The next closest QB is Lawrence at 5-112, then Howell for 5-83. In comparison, Fields only has 1-10 yds. Insane how bad the refs are against the Bears. No DPI calls on the other team (Mooney), and a lot missed roughing the passer calls on Fields.
