While not the best, the Romo Witten connection resulted in 786 receptions.
Gronk and Brady are in the high 500 and Rivers/Gates were at 774.
Now Gronk and Gates found the endzone way more than Witten but Romo and Witten were definitely on the same page when it came to chemistry and knowing where to throw/where to be.
The fact they put Carr-Waller on the list is laughable when it comes to an all time list.
