Atlanta Falcons
As a rookie, he played in 15 games and recorded 37 receptions for 437 yards and one touchdown. In 2008, rookie Harry Douglas and the return of Brian Finneran from a two-year absence, led to Robinson falling on the depth chart. That season, he played in only six games because of head and hamstring injuries, making 5 receptions for 52 yards.
St. Louis Rams
On April 7, 2009 the Falcons traded Robinson and its fifth round and sixth round draft choices to the St. Louis Rams, in exchange for their fifth round and sixth round selections.

At the time, he was leading the team in receptions with 13 for 167 yards. In 2010, he had another dismissive season, he appeared in 14 games, finishing fifth on the team with 34 receptions for 344 yards and 2 touchdowns.

He was released on September 13, after suffering a hamstring injury during his first practice.

During the week eight loss against the Philadelphia Eagles, he had five catches for 103 yards and a touchdown, his first as a Cowboy.

Jacksonville Jaguars
