"He's big enough to play guard and he can play center as well, so that really helps us out," Lions general manager Martin Mayhew said of Swanson. "We really like this guy.
"Very, very, very smart kid. He's 6-5, 312. He's got 50 straight starts in his career, so he's durable. I think he's gonna be a great fit for us, probably play some guard for us in the preseason. Wash will work with him on that some."
Wash is Lions offensive line coach Jeremiah Washburn, who also played center and guard for Arkansas.
"I am excited to get an Arkansas guy in here," Washburn said. "For us, he fits the profile of the guys we want in our room -- experienced, tough, smart, versatile."
For his part, Swanson is excited to learn from Raiola.
"I do know Dominic, who's been in the NFL for years, years upon years," Swanson said. "I just can't wait to meet him and just pick his brain about the things that he knows."
The Lions are hoping for the same kind of success they had with another SEC offensive lineman they selected in the third round, Kentucky's Larry Warford, who started 16 games as a rookie.
"Obviously, he was a household name in the SEC years ago, so I do know of him," Swanson said. "I know he came in this last year and did a great job."
Because the SEC is considered the top conference in college football, Swanson has faced a high level of competition.
"I'm an SEC guy," Washburn said. "I make no apologies about it. It is a litmus test for offensive linemen. Larry played against the best, Travis played against the best. I would expect them to be a little more NFL-ready."
The Lions are also excited about the fact that Swanson started 50 straight games at Arkansas.
"Anybody that obviously plays consecutive games like that, it's not because of the fact that he didn't suffer injuries," Lions coach Jim Caldwell said. "Typically, what that tells you is he played through them."
