What It Means:

Riley Reiff was expected remain on the left side in the final year of his rookie deal, but he was playing right tackle on Thursday. This is just one offseason practice, but the Lions have been fairly open about their desire to move Reiff to the right side. Decker was not seen as the player who would facilitate that switch by people outside the organization, but it seems Detroit has other ideas.

Detroit was a middle-of-the-road offense in 2015, ranking 16th in Adjusted Offensive Net Expected Points per play.
