Things weren't helped this spring when a number of players were hampered by injuries that limited their participation, leaving the picture just as murky as it was when last season ended.
But, according to linebackers coach Don Pellum his group's health is not a major concern entering fall camp.
"I think right now we're pretty healthy. I think right now, all the guys are out there," he said following Tuesday's practice.
And like fans and media alike, Pellum doesn't know who will start the season opener versus Nicholls State, much less what a two-deep rotation would look like.
"We're going to let those guys to fight it out and compete and see in a couple of week who rises to the top," he said.
Among those competing for field time will be three freshman, Tyrell Robinson, Torrodney Prevot and Danny Mattingly. And since Pellum has only seen the trio in an Oregon uniform for two days, projecting their involvement this fall would be silly, but Pellum said each has "special gifts."
"Torrodney runs really well, I think he shows some ability to maybe rush the passer.
"Tyrell Robinson is a phenomenal athlete. I think he has the potential to help us in the pass rush from the front standpoint and he may be one of our better cover guys. He has a unique athleticism for our position that will allow us to do a lot of things with him as he grows into the defense.
"Mattingly has the right stature and the right attitude and I think he can help us.
Pellum also confirmed what many had speculated that Tyrell's twin brother Tyree will be part of the secondary, where he says he'll play safety.
