The Los Angeles Rams made a few changes to their offensive line this offseason, bringing in Andrew Whitworth to replace Greg Robinson at left tackle. The former Bengal will be a huge upgrade over Robinson but the rest of the line remains a work in progress.

First-year coach Sean McVay made that evident during Sunday’s practice, shuffling around the front five. He switched right guard Rob Havenstein and right tackle Jamon Brown, giving each player a look at a new position. McVay explained his decision to mix up the right side of the line afterwards, essentially calling it a backup plan.

“Just like we always do; we’re really just trying to figure out the best combination in terms of how we want to do things,” McVay said during his post-practice press conference. “I think we feel really good about what Jamon and Rob have done on that right side, but with Rob’s history playing tackle and Jamon’s history playing guard, we also want to have contingency plans in place if one of them were to go down.”

Brown played all over the offensive line last season, making appearances at every spot except center. Havenstein doesn’t have the same position flexibility that Brown has, but he has experience playing both right guard and right tackle.

Considering the lack of depth Los Angeles has on the offensive line, it should come as no surprise that McVay would want to fiddle around with the unit to determine if they can get by should a starter go down.

When the Rams kick off their preseason slate on Saturday night against the Cowboys, the offensive line will be a focal point. It remains to be seen which combination McVay will go with in his first game as the team’s head coach.
