Trestin spent the first three weeks on the practice roster, but started the next 13 games before going down with a season-ending knee injury during a career-high six-tackle performance in October at Saskatchewan. In 2009, he recorded 34 tackles and three pass knockdowns and also returned nine punts for 68 yards.
Trestin began his college career as a running back but was moved to defense after his freshman season. He played in 46 games as a Spartan (’02-’05) and compiled more than 1,300 all-purpose yards including 1,000 yards on punt and kickoff returns. A versatile and gifted player, he scored a touchdown five different ways (rushing, receiving, INT return, kickoff return, punt return) during his career. On defense, he accumulated 148 tackles and five interceptions in three-plus seasons as a defensive back.
Trestin, whose name means "noble warrior" in German, chose San Jose State so he could remain close to his mother, Renee, who suffered a stroke November 2001. His poem, "Intro," was published on poetry.com and he was invited to participate in the 2002 International Society of Poets contest in Orlando, FL. In 2005, he was one of four Spartan football players featured in the Public Broadcasting System documentary, Playing for Keeps. He was also the subject of a documentary: The Trestin George Story produced by a film company called Spring Street Studios.
