Packers are 2nd in the league in pass plays over 25 yards.
You said 20 yards before, in which they're T4. Last year they were T1 in 40+ yard passes, this year their T19.
Like I said, the sample size isn't big enough there.
One thing is indisputable though, and that's the fact that Jordy averaged 15+ YPR career, and Cobb and Jones are around 13 YPR.
He's produced the big plays in this offense over the last 4 years. There's no debating it.
