Back to Clem's OL situation

This seemed to be brushed off like no big deal. I'm intrigued. 

Anthony started in 5 games last season and has since been listed as the backup tackle in both spots on the OL. Who is going to back up both tackle spots? Moving guards to tackle is a big no no from what I've heard. Sign of weakness on the OL if I remember correctly.
