In his first year of eligibility, it’s no surprise that Junior Seau was voted as one of the 15 finalists for the Pro Football Hall of Fame.

Seau belongs in the Hall just by looking at the numbers. He played 20 seasons for three different teams, was voted to the Pro Bowl 12 times, and was named first-team All-Pro eight times. Seau played in 268 games, the second most of any linebacker in NFL history. He finished with 1,522 tackles, 56.5 sacks and 18 interceptions.

Seau played in two Super Bowls, including the Chargers' only Super Bowl appearance in franchise history. He was named to the 1990s All-Decade team by the Pro Football Hall of Fame.

But along with those impressive accomplishments, the energetic Seau imposed his will on opponents with his aggressive style of play. Seau played with an infectious energy and flair that forced fans to watch his every move, because you never knew when he would create a memorable moment on the field.
