Establishing the receiving corps
The 49ers have questions at receiver, but it isn’t due to a lack of talent. They have a slew of options to fill out the roster after Deebo Samuel, Kendrick Bourne and rookie Brandon Aiyuk. That trio will all make the team, but after that it’s all up in the air. San Francisco has the pieces to put together a really strong group of pass catchers, but ironing out which three or four other players will join the Samuel-Bourne-Aiyuk trio is likely going to take the entire preseason.
