4. Daniel Helm
Helm broke into the NFL last season with the Chargers as an undrafted rookie out of Duke. He spent some time in Los Angeles before getting released and landing with the 49ers in early August. He spent most of the year on the practice squad, but was elevated to the active roster in mid December. Helm is another player who can play as a move tight end, but he produced more as a receiver with the Blue Devils (69 catches, 767 yards, 6 touchdowns). He’ll need to undergo a pretty significant improvement in the offseason to carve out a roster spot.
