There's not a higher-variance position on the San Francisco 49ers roster this season than wide receiver.
The 49ers have a ton of question marks at wide receiver thanks to injury, potential suspension, a rookie and two players entering their second seasons. San Francisco selected Ricky Pearsall in the first round last year. Three rounds later they selected Jacob Cowing. With Aiyuk's status to start the season unknown, and not a ton of depth on the roster behind last year's leading receiver Jauan Jennings, Pearsall and Cowing will get pushed to the forefront to compete for snaps.
