This is PROBABLY something people already know...but perhaps it's a good reminder.
Every one of Dion Jordan's 5.0 sacks came before he suffered his shoulder injury toward the beginning of the Colorado game. To that point he had 5.0 sacks, 7.0 TFLs, 2 forced fumbles and 29 tackles in 7 games. After the injury, he had 0.0 sacks, 3.0 TFLs, 1 forced fumble and 11 tackles in 4 games. The surgery he needed was for a torn rotator cuff.
That's the thing if you get caught up watching the Stanford, USC, Oregon State or Kansas State games. If you're seeing something missing from his game in those films, there's probably a reason. Probably should look more to the Fresno State, Arizona State, Washington State, Arizona and Washington games for good footage on him.
