Bierria came to UW as a mid-level three star recruit (whose point person was, incidentally, Jacob Sirmon’s uncle Peter) from Narbonne High School in LA. After redshirting in 2013, he was a part of the youth movement of Chris Petersen’s first season, playing in all 14 games and starting four of them. His sophomore year was widely regarded as his (and linebacking partner Azeem Victor’s) breakout year, where he started all but one game and began showing his knack for both fumble recoveries and forcing fumbles. If there’s one performance that stands out from his sophomore year — and, indeed as the turning point of Chris Petersen’s program — it would arguably be in the upset win against USC, where he had eight tackles, two of which were for a loss and one of which was a sack of Cody Kessler.
