The Chargers need help at the wide receiver position. Besides stars Keenan Allen and Mike Williams, there are not many capable players in-house. That may prompt the Chargers to search for a WR3 and additional depth in free agency, the draft or both.
It is almost certain that the Chargers will draft at least one receiver, as Tom Telesco will probably look to bolster the wide receiver group in a very deep class at the position.
The free-agent class also has enough quality and quantity for the Chargers to search for a receiver with the characteristics they like.
