Chicago Bears left tackle Charles Leno is having a tremendous preseason and may be on the cusp of emerging as one of the NFL’s premier blindside protectors.

He’s playing like one right now, according to Pro Football Focus. Leno is the highest-graded offensive tackle in pass protection so far this summer.

If Leno develops into an elite player this season, the Bears will benefit beyond just the offense’s effectiveness. Leno’s four-year, $37 million contract signed last offseason will instantly become one of the team’s best bargains at such a premium position.

In order for Mitch Trubisky and the Bears offense to thrive, he needs to have confidence in his protection up front. Leno is the most important part of developing that trust, and he’s taken a huge step in that process over the last couple of games.
