That's a direct result of snaps.
Diggs was managed and played far fewer snaps than an average #1.
Diggs had 598 snaps, 55% of the teams offensive snaps. 103 targets which means he was targeted 17% of the snaps he played.
AJ had 121 targets on 843 snaps. So he was targeted on 14% of the snaps he played.
AJ was targeted less when he was on the field than Diggs.
AJ being on the field more doesn't mean we have to change our offense.
Diggs was managed all year coming off injury, that is the only reason his snap count was so low, not because our O was built that way.
