ALLEN PARK -- While there is competition between Jason Fox and Corey Hilliard for the starting right tackle spot, left tackle belongs to Riley Reiff.

Reiff was drafted in the first round in 2012 to eventually fill the shoes of Jeff Backus. He got one start in 2012 for the one game Backus missed in his dozen years playing for the Lions. Reiff also saw regular playing time lining up as a tight end.

“Riley is doing great, he is,’’ offensive coordinator Scott Linehan said on Wednesday. “Everything we’ve asked him to do, step into a role. When we drafted him that was the role we envisioned for him. We didn’t set that as the only possibility. He’s done a great job there and he’s making progress every day. ... We feel really, really confident in his ability to do a great job for us.’’

Hilliard and Fox have been alternating at right tackle with the starters through OTAs and minicamp.

“We’ll keep them as equal as we can and let guys work with different groups,’’ Linehan said. “... We’ll try to keep it to where their rotation seems to be similar from Day One. You might do something different and maybe flip it the next day.’’
