From the video
Aiyuk, Aiyuk's been a massive faller. You do have Tristan Wirfs looking like he's going to go for tonight, and at the same time, you possibly have Mike Evans. Now, technically, if you look at the splits with and without Mike Evans, Aiyuk's been a much better wide receiver when Evans has been playing. I don't necessarily think that Mike Evans being in this offense taking target volume is going to make Aiyuk better in fantasy. It'll definitely make him more efficient, but I think the volume will go down.
STACKED’s take

Massive faller; efficiency better with Evans but volume likely declining
Massive faller this season. Averaging 13.5 fantasy points per game and remains WR1 in offense, but trend is concerning. With Tristan Wirfs expected to play and Mike Evans possibly available, Aiyuk's efficiency improves when Evans plays (better splits with Evans in lineup), though volume expected to decline rather than increase when Evans returns.
