Dwight attended the University of Iowa, where he played for the Iowa Hawkeyes football team. He finished his college career with Big Ten Conference records for punt return yardage (1,102) and punts returned for touchdowns (5); his yardage mark has since been eclipsed by three others and Ted Ginn Jr. surpassed his return touchdown mark. Dwight held the Hawkeyes team record for career receiving touchdowns (21) until 2011, when his mark was surpassed by Marvin McNutt. He held the team record for career receiving yards (2,271) until 2010 when Derrell Johnson-Koulianos became the all-time leader in receiving yards. In 1997, Dwight was a consensus first-team All-American and finished seventh in the balloting for the Heisman Trophy.
Dwight also competed in track events, with personal bests of 10.31 seconds in the 100 meters and 20.98 seconds in the 200 meters; in 1999, he was Big Ten Champion in the 100-meter dash, and he also was a member of the Big Ten champion 4x400-meter relay and 4x100-meter relay teams in 1999, and the Big Ten champion 4x100-meter relay team in 1998.
Dwight was drafted in the fourth round (114th overall) of the 1998 NFL draft by the Atlanta Falcons.[3] In Super Bowl XXXIII, he returned five kickoffs, including one for 94 yards and a touchdown. He is second all-time in Super Bowl kick return yardage for a single game (210), and his 42.0 yards per return in the game was a Super Bowl career record. Dwight is also known as "The Man".
San Diego Chargers
After three seasons with Atlanta, Dwight was traded on April 20, 2001, to the San Diego Chargers as part of the deal that enabled the Falcons to select quarterback Michael Vick with the 2001 draft's top selection (which the Chargers originally held pursuant to their 1–15 record in 2000).

Accomplishments and reputation
Despite being only 5'8" tall and weighing 185 pounds, Dwight was a prolific punt and kick returner during his career. He was labeled "injury-prone" because he rarely played a season without missing a significant number of games. The 2005 season was the only season in which Dwight appeared in all 16 of his team's games. Dwight's most productive seasons as a wide receiver have been 1999, when he caught 32 passes for 669 yards (a 20.9-yard average per catch) with seven touchdowns, and 2002, when he caught 50 passes for 623 yards. He also scored five return touchdowns in the NFL, three on punts and two on kickoffs.
Dwight has a number of interests outside football. He founded the Tim Dwight Foundation to help needy kids with scholarships and provide assistance to the Children's Hospital of Iowa. He also owns his own yoga studio in Iowa.
In 2007, The Cedar Rapids (Iowa) Gazette sports staff voted Dwight the all-time greatest athlete from that newspaper's circulation area, topping other notables like NFL quarterback Kurt Warner and 2007 Masters champion Zach Johnson.
