Fast forward several months and Rogers is no longer a part of the program and Dallas is back catching footballs instead of defending them.
Dallas is a sophomore from Ellenwood, Ga., that finished his freshman season with three catches for 37 yards and is now one of just three wide receivers returning in 2012 with a career catch in the orange and white.
"I am very excited," Dallas said of the move Monday. "I just wanted to do whatever to help my team and it was just another decision that I made. I am just coming to make plays. It was just like I never went anywhere."
After spending most of the preseason at defensive back, Dallas says he gained knowledge that could be helpful in his transition back to the offensive side of the football.
"It helped me a lot," he said. "Reading coverages, just learning the game, just reading coverages, seeing them and executing. When I came back to wide receiver I already knew everything so it was just like I never missed it."
Dallas, a 5-foot-11, 187-pounder says he feels far more comfortable at wide receiver.
"Vincent is fine," quarterback Tyler Bray said. "He was only at DB for a couple of months. He came back, he knows all the plays and kind of started where he left off."
As a senior at Cedar Grove (Ga.) High School, Dallas was an All-State wideout after racking up 52 receptions for 949 yards and seven touchdowns and head coach Derek Dooley thinks he can help the Vol offense.
"Pig (Alton Howard) and (Jason) Croom have been out and we all of a sudden got thin at wideout," Dooley said. "That is where (Dallas) was and he wasn't in our two-deep at corner. He has a chance to play for us. He has done good. He is really excited I think."
Dallas worked with the second team offense and reportedly hooked up with Bray on Sunday, his first day back at wide receiver, for a long touchdown pass.
