I could see Matthews being somewhat eased in on the edge with ‘reduced’ snaps until he’s truly back to 100% game speed.
Besides, I think the Rams want to see snaps at edge for some youngsters to better determine whether they might have a potential Fowler replacement already on the roster. Could have a huge impact on their ‘20 FA and draft strategy.
I could also see Matthews getting some of the Reeder snaps inside. For reasons that seem obvious.
