Spielman played eight seasons with the Lions (1988–95), where he was a defensive stalwart during the team's run to four playoff appearances, two NFC Central titles, and a berth in the 1991 NFC Championship Game. He captained the Lions' defense that was one of the best statistically in the NFL in the mid-1990s. Spielman is the franchise's all-time leader in career tackles with 1,020 (since the team began recording tackles statistically in 1973.) He also recorded 10 sacks, four interceptions, 30 pass defenses, 13 forced fumbles and 17 fumble recoveries during his Lions' career. He was the first Lion to lead the team in tackles seven consecutive seasons since 1973, including the team's highest single-season tally 195 tackles in 1994.
