Below is a screenshot of the lowest separation of skill position players through 1st 2 weeks of the season (no qualifiers applied).  Bears have 3 of the top 5.  I don't know whether the QB decisions play into the separation or if this is a pure stat - but not even the best QB's can consistently deal with this many people NOT getting open.  All of these parties need to step it up - the really scary one is Miller - he is supposed to be more electric at getting open; Robinson has always had less separation than the league but made up for it with fundamental awesomeness.  

 

Damn, I noticed this out of the WR's but didn't think anything of it at the time. It might be the routes, but even on that Miller TD catch against DET, he had very little separation against a backup DB. 

With the amount of cushion Robinson gets you would think the catch rate would be a little higher. Both WRs are dropping a lot of balls.

If you compare these players (CHI and MIA) with their QBs, then look at others around the league, I don't see any correlation between QB and separation. For once, it looks like Trubisky is not the main problem on offense. With the O-Line and running game going, it looks like the receiving corps is failing.

At the same token, Trubisky's QBR is at 54.2, 23rd in the league behind Jeff Driskel and just ahead of Daniel Jones and Joe Burrow. We need him playing around #15 to have a chance at a playoff run. 

Some promising notes about Trubisky, using the NextGen Stats, his average air yards to sticks is +1.8, tied for 3rd in the league. Traditionally Trubisky has had a negative value, meaning he was always throwing short of the sticks. 

Another one is aggressiveness, he is actually #2 in the league at 34.4%. So he is taking more shots down the field.

Through 3 games this year, his numbers don't look much different than Mahomes or Watson's. That is all pointing to improve behind Center. Now we need a little more timing and feel for ball placement on certain routes, and we should see more improvement.
