Wow, look at that! As soon as you asked, they through out a Jackson Avila Shelton Anchrum
BOOM lineup today! Boom got snaps at both RG and RT
Yes, McVay said Bruss is 2nd RT but they may view Jackson and Boom as a top 6 lineman on the team, which can explain why both had snaps at 3 different positions with the starting OL unit.
I think it depends on how Bruss plays in the preseason. He missed an entire year of development and has had limited snaps. If he plays well, he could be next in line if Hav is out. But if he's still raw, I can see both Boom and Jackson out there with the starting lineup.
