49ers coach Kyle Shanahan has once again addressed the curious situation of wide receiver Brandon Aiyuk.
The second-year wideout's sophomore slump has puzzled fans all season, and Shanahan to this point has offered little clarity, previously denying that Aiyuk was in his "doghouse" and blaming "fantasy football" for the intense scrutiny on Aiyuk's usage.
The 2020 first-round draft pick was a surprise breakout star as a rookie after stepping in for the injured Deebo Samuel early in the season, but Shanahan has indicated that Samuel has just been flat-out better in 2021.

I think he's still trying to get back to that point, which I think he's closer to that point right now than he was a couple of weeks ago because he has been working hard and tryin
