Entering the season, the Oregon Ducks have arguably the nation’s No. 1 offensive line and a head coach who knows exactly how to maximize its potential.

However, the future is less clear.

While Mario Cristobal’s presence is solidified, Oregon will lose seniors Jake Hanson, Shane Lemieux, Calvin Throckmorton, Dallas Warmack, Brady Aiello and George Moore after the season, forcing the Ducks to reload the group.

Last week, Oregon had two offensive line commitments and several spots remaining.

But that has changed quickly.

The Ducks added Jonathan Denis, the nation’s No. 6 guard, and projected tackle Jaylan Jeffers, who held offers from LSU and Michigan.

On Friday morning, Cristobal added yet another piece to his favorite position group, as T.J. Bass, the nation’s No. 2 junior college offensive guard, announced his commitment to Oregon over offers from Arizona State, Auburn, Kansas State, TCU, UCLA, Utah, Washington State and West Virginia:

The 6-foot-5, 305-pound lineman, out of Butte College (Oroville, California), took an official visit to Oregon during its “Saturday Night Live” event, but did not participate in the events.

He joins Denis, Jeffers, 6-foot-7, 390-pound offensive tackle Faaope Laloulu and 6-foot-4, 290-pound guard Marcus Harper as part of a current five-man offensive line haul in the class of 2020.
