He played a valuable role on special teams as well.

Douglas saw an increased role in 2005 with the departure of J.R. Russell. His first career receiving touchdown came in a 3 catch, 91 yard performance against Oregon State in which the Cardinals won, 63–27. Against arch-rival Cincinnati, he had a career-high 5 catches for 87 yards and a touchdown in a 46–22 victory. Douglas finished the year with 27 catches for 457 yards.

He started off the year with a 26-yard run off a reverse against Kentucky that set up a 48-yard score by Michael Bush in a 59–28 win. Against Miami, despite scoring no touchdowns, he had a big game catching 4 passes for 94 yards on his birthday. He caught a touchdown pass from Hunter Cantwell the next week at Kansas State in a 24–6 win, and went on to catch 5 more, 2 in the season finale against Connecticut. In the 2007 Orange Bowl, he registered a personal best and an Orange Bowl best 10 catches for 165 yards in a 24–13 Cardinals win. He and teammate Mario Urrutia proved to be one of the best receiving tandems in the entire nation. Douglas started off 2007 with a bang, catching 5 balls for 151 yards and 2 scores in an easy win over Murray State. He caught a touchdown pass in each of his team's next 3 games against MTSU, Kentucky, and Syracuse before suffering an injury. He returned on October 13 against Cincinnati, catching 7 passes for 118 yards, none of which was more important than a 51-yard reception that set up a game winning touchdown by Anthony Allen in a 28–24 win. To close out the year, he caught a touchdown in a 24–17 win over Pitt and came up with a great performance despite a 55–17 loss at South Florida, recording 8 receptions for 136 yards and 1 touchdown.

2013
Douglas had a career-year in 2013. He played in all 16 games and racked up 1,067 yards on 85 receptions with 2 touchdowns.

After that play, a brief scuffle ensued between Douglas and Broncos cornerback Aqib Talib. Many current and former players, as well as journalists considered the hit "dirty".
