Smith's numbers dropped off a bit in 2002 as he ran for 982 yards and 6 touchdowns. He did get more involved in the passing game however, and caught 31 balls including 2 touchdowns. 2003 was Smith's final season in New England and he managed just 642 yards, although he still led the team in rushing. His play improved in the playoffs that year as he ran for 252 yards and 2 scores as Smith and the Patriots won their second Super Bowl championship, Super Bowl XXXVIII. Smith joined the Titans for 2004 and he ran for 509 yards. It was the only season in his career in which he failed to record a single 100 yard game.

For his career Smith played in 131 games, running for 6,881 yards and 54 touchdowns, good for 50th and 44th on the all-time lists respectively.
