Outlook: At the time Swanson suffered a concussion last year and missed the final five games of the regular season, he was graded as the ninth-best center in the league by Pro Football Focus.
In 12 games last season, Swanson allowed just two sacks, three quarterback hits and seven hurries. He was one of Detroit's most consistent and reliable offensive linemen alongside left tackle Taylor Decker.

Swanson's been fully recovered from that concussion for months now, and has no limitations in training camp. He enters this season as the clear-cut No. 1 center and one of the leaders upfront for Detroit along their offensive line.
Practice: Swanson had a pretty sharp practice Friday in Indianapolis, which has become the norm for him.
He was solid in one-on-one drills with the Colts defensive linemen, and easily won his rep against nose tackle Al Woods.
He also delivered a pancake block on Woods in a team session on a run play.
Swanson seems very comfortable making the line calls -- vocal and decisive. In one team rep, he did a nice job to spring a run play by getting to the second level and putting a nice block on Colts linebacker Edwin Jackson.
Quotable: "This is now two and a half years in this offense, so, thankfully, we've been able to keep this offense for a while now," Swanson said after Friday's practice. "Every year you're a part of it you become more comfortable.
"I like how things are going right now just as far as my comfort level with calls and what to do."
