ENGLEWOOD, Colo. — When the legal-tampering period began Monday, the Broncos moved quickly to reportedly agree to terms with guard Graham Glasgow.

It's a move that could instantly solidify the interior of the Broncos' offensive line.

The former third-round pick has experience playing left guard, center and right guard — and he has missed just two games during his four-year career.

While playing right guard in 2019, Glasgow did not allow a sack and he had just three penalties enforced against him all season. The previous year, Glasgow allowed just one sack as he saw extensive time at center.

Glasgow's play also appears to be on the rise; he turned in his best season of his career in 2019, according to Pro Football Focus.

With Connor McGovern reportedly agreeing to terms with the Jets, it's too early to project whether Glasgow will slot in at center or right guard for the Broncos. As the team approaches the second wave of free agency and the draft, they could choose to add at either position.

Already clear, though, is that the Broncos have reportedly added a player that was perhaps the top interior lineman on the open market.

A review of the Lions' Week 17 game against the eventual NFC finalist Green Bay Packers makes Glasgow's talent quite clear.
