The 49ers don’t exactly have a problem at wide receiver, but there are definitely questions at WR3 and beyond. Trent Sherfield initially looked to only contribute on special teams when he signed in March. Sherfield showing he’s more than a special teamer and can impact the game as a pass-catcher is great for the receiver room.
In Deebo Samuel’s absence, Sherfield got reps with the starters yesterday and got open at every level. I think Sherfield could be used in Kyle Shanahan's offense similarly to Marquise Goodwin. Goodwin wasn’t the best route runner, but Shanahan moved him effectively in 2017.
