Kline was a 1999 All-Mountain West Conference selection and manned the right guard position on what was considered by many one of the finest offensive lines in San Diego State history.

During his senior season, he graded out at 88.6% and made 38 knockdowns and registered 33 other big blocks the most among the team's offensive lineman—and a school record.

Kline is the founder and managing director of Park Lane, an investment bank, merchant bank, and principal investor that provides advisory services to sports teams, sports based businesses, early stage companies, and some of the largest real estate investors in the world.

Some of Park Lane's clients include NHL, NBA, NFL, and MLB teams and owners as well as other sports based businesses.

Kline now lives in Los Angeles, California, and enjoys collecting art, playing rhythm and lead guitar in a blues/rock band, and can be seen surfing up and down the coast.

He is active in his community and is the founder and Director of Project PLAY!, a not-for-profit foundation that provides funding for sports, music, and art youth programs in Los Angeles.
