Answer by taking a quote from the following article:

Tiaina Baul Seau Jr. (; SAY-ow; January 19, 1969 - May 2, 2012), better known as Junior Seau, was a linebacker in the National Football League (NFL). Known for his passionate play, he was a 10-time All-Pro, 12-time Pro Bowl selection, and named to the NFL 1990s All-Decade Team.

After three years as a Trojan, Seau entered the NFL draft after his junior season and was chosen in the first round of the 1990 NFL Draft by Bobby Beathard's San Diego Chargers as the fifth overall draft selection. Seau quickly became one of the most popular players on the Chargers, receiving the nickname "Tasmanian Devil", after the wild antics of the cartoon character. He became the face of the Chargers franchise and a San Diego sports icon.  Seau started 15 of the 16 games he played in during his rookie season, and was named an alternate to the 1991 Pro Bowl after recording 85 tackles. In 1991, he picked up 129 tackles and seven sacks and was named to the 1992 Pro Bowl, the first of 12 consecutive Pro Bowls for Seau. He was also voted NFL's Defensive MVP by the Newspaper Enterprise Association AFC Defensive Player of the Year by United Press International, as well as the NFL Alumni Linebacker of the Year and the NFLPA AFC Linebacker of the Year.  He started no fewer than 13 games for the Chargers over each of the ensuing 11 seasons, registering a career high with 155 tackles in 1994. That year, Seau was named NFL Defensive Player of the Year by United Press International, and he led his team to a championship appearance in Super Bowl XXIX. In one of the greatest games in his career, he recorded 16 tackles in the 1994 AFC Championship Game while playing with a pinched nerve in his neck in a 17-13 victory over the Pittsburgh Steelers. In 2002, his final year with the Chargers, he logged a then-career low 83 tackles and missed his final Pro Bowl with an ankle injury.

Did he win any awards with San Diego?
