The Detroit LIons coaches could have a starting offensive line written in pencil, but there are plenty of questions heading into training camp. LaAdrian Waddle’s health is an issue. He had ACL surgery in January. 

Will he be ready for training camp or preseason games? No one is saying. If he’s healthy he seems to have the lock on starting at right tackle.

Here’s how the starting roles along the offensive line are shaping up:

1. Left tackle — This is Riley Reiff’s job.
   
   
2. Left guard — This could get interesting. Veteran Manny Ramirez, who was acquired during the draft in a trade, was with the starting group during the mandatory minicamp. First-round pick Laken Tomlinson is in the conversation for the start here but will have to earn it in camp.
   
   
3. Center — It seems likely that Travis Swanson will get the start. There are three other centers on the roster at this point — veteran Taylor Boggs, Braxston Cave and Darren Keyton (Central Michigan). One of those three will have to step up big time in camp to over-take Swanson.
   
   
4. Right guard — Expect Larry Warford to start for the third straight season. He’s humble and says he knows he has to earn his spot back as a starter, but he is the favorite.
   
   
5. Right tackle — Again, if LaAdrian Waddle is healthy he probably will start. If not, Cornelius Lucas who started three games in 2014, is likely the favorite. They’ll all be pushed by Xavier Proctor (who moved from defensive end), Michael Williams (who moved from tight end) and seventh-round pick Corey Robinson.
