EUGENE -- Oregon's offensive line will face one of its biggest tests of the season this week at Arizona - literally.
Wildcats defensive lineman PJ Johnson, a junior college transfer, has quickly made an impact thanks to his 6-foot-4, 335-pound frame.
There are few defensive linemen in the Pac-12 larger than Johnson, with UCLA's Atonio Mafi (6-foot-2, 380 pounds) and Oregon State's Elu Aydon (6-foot-3, 378 pounds) as the rare exceptions but neither is anywhere near as disruptive. Entering Saturday night's game, Johnson has 21 tackles with 6.5 for loss including a team-high three sacks and Arizona lines him up both at nose tackle and defensive end.
