The Detroit Lions have sunk a ton of resources into their offensive line over the last 13 months, and left tackle Taylor Decker said it’s incumbent upon the group to prove why on the field.

“Obviously, the organization and the front office thinks that (if) you build well up front, the team will be good,” Decker said. “I don’t want to project too far ahead, but I think we do have a hardworking group and a group that meshes well with everybody’s personalities.”

The Lions have replaced four of their five starters on the offensive line since Bob Quinn took over as general manager last January, drafting Decker and left guard Graham Glasgow last year and signing Rick Wagner and T.J. Lang as free agents this off-season.

Center Travis Swanson, a 2014 third-round pick, is the only holdover starter from 2015 on the offensive front.

“It’s really cool to see that this organization’s putting an emphasis on offensive line,” Decker said. “They drafted three of us the other year with me, Graham and Joe (Dahl) and they’re bringing in obviously documented very good players.

“I think it’s going to help get in kind of a different perspective on things, guys that have played in different systems, maybe they can help me with a little thing here and there. And a bunch of little things here and there make you a lot better player.”

So far, the unit has been together for just four weeks of workouts — Organized Team Activities start May 23 and mandatory minicamp follows, and Lang won’t take part in either as he recovers from January hip surgery — but Decker said they’ve already started to form a bond.

“I think (Lang and Wagner) fit really well as personalities in the room,” Decker said. “They’re obviously smart football players. They wouldn’t have been as highly touted, tons of teams wanted them, if they weren’t. Obviously, we haven’t done a ton of on-the-field work yet, but I think it’s well documented that they’re capable football players and it’s just cool that they fit well with the personalities in the room. I think it’s probably something that the front office and the organization was looking for.”
