Belichick is the greatest defensive mind n the history of the NFL, but there have been issues on the OL since the rising star Cole Popovich was dumped because of fearful idiocy by the league office.
Popovich may or may not be a good OL coach, I really don’t know, but the issue with the OL really goes to Scar retiring, and the challenge of replacing possibly the GOAT OL coach. As for drafting a LT high in the last draft goes it would have been a waste of a first round pick, as this was a really weak first round at OT, and they were able to get a great CB prospect with their first.
