Josh Huff's departure to the NFL leaves Oregon to replace its No. 1 target. Losing De'Anthony Thomas to the pros eliminates another proven commodity from the Ducks' passing attack.
Add Bralon Addison's knee injury, suffered during practice last month, and Mariota is essentially working with an entirely new corps of receiving targets.
Between Huff, Addison and Thomas, Oregon has lost 2,276 yards and 20 touchdowns of production in the passing game from a season ago.
Redshirt senior Keanon Lowe is no stranger to the program, and he's welcomed a role as the unit's leader.
"He’s doing a great job on the field being a leader and being more vocal. He’s almost to the point where I have to tell him to be quiet," offensive coordinator Scott Frost told Tyson Alger of The Oregonian.
Now Lowe's production must match his veteran savvy.
Redshirt freshmen Devon Allen and Darren Carrington both impressed in the spring, culminating with standout performances in the intrasquad scrimmage. Helfrich said on the Pac-12 teleconference call that each "showed flashes."
Sustaining those flashes in live-game situations is a different challenge, and one they must meet to make this Oregon receiving corps formidable.
