Riley Reiff might not know about his fifth-year option and may not know what his exact position will be with the Detroit Lions in 2015, but one thing is obvious as of now.

The offensive tackle is going to play and play somewhere -- it’s just a question of being on the left side or the right side.

“He could play both, to be honest with you,” Lions coach Jim Caldwell told reporters at the owners meetings Wednesday. “He could play both and not have an issue. Play extremely well. Let me put it to you this way.

“Any time you put a guy at the left tackle position, he could play right. Trust me. And this guy can play left.”

Reiff has been Detroit’s starting left tackle for the past two seasons and was one of the Lions’ top linemen in 2014. Yet questions were raised about where Reiff could play in 2015, especially when general manager Martin Mayhew would not commit to a position for Reiff at the NFL combine in February.

That lack of commitment to a certain spot for Reiff continued at the owners meetings and could be dictated by both the draft as well as the health of right tackle LaAdrian Waddle coming off a knee injury last season.

Positional flexibility, both with positions and sides of the line, has been paramount for Detroit this offseason. Mayhew praised the value of versatility at the combine and Caldwell explained the necessity for it at the owners meetings Wednesday.

He believes his top three tackles as of now -- Reiff, Waddle and Cornelius Lucas -- all have that type of flexibility to play either right or left tackle.

“That’s the beauty of it,” Caldwell said. “So we can kind of do whatever best suits us. It kind of depends, Waddle coming back, where he’s going to be, those kinds of things in terms of injury, just kind of get a feel for that.

“See what happens in the draft in terms of where we fill some spots. Make your adjustments accordingly. That’s the thing about coaching that you have to understand is in coaching, you have to find a way to put your guys in the best possible position to be successful. You don’t want to pigeonhole people.”

This leads to the other question about Reiff and his position this offseason: Could he move inside to guard, where the Lions have a gaping hole on the left side as the team tries to sign either Justin Blalock or Rob Sims?

Caldwell didn’t think that would happen, at least for now.

“Not today, I don’t,” Caldwell said. “But like I said, you never say never.”
